This page provides a complete technical and commercial overview of both the Low Voltage Residential Series and the High Voltage C&I Series. From cell chemistry and safety architecture to inverter compatibility, certifications, and OEM/ODM options — every decision factor is addressed below.
The LV Series operates at 46.4V–57.6V (51.2V nominal), making it the ideal residential energy storage solution compatible with mainstream 48V/51.2V hybrid inverters. Available in rack-mount, wall-mount, and wheeled floor-standing form factors, LV modules range from 5.12kWh to 16kWh per unit and support up to 15 units in parallel — reaching a maximum system capacity of approximately 240kWh.
Best for: Residential solar installers, small EPC projects, off-grid systems, and distributors targeting the home energy market.
The HV Series connects 5 to 17 battery modules in series, producing system voltages from 185.6V to 979.2V. Individual systems range from 80kWh to 225kWh; up to 4 systems can be paralleled to approach 900kWh in a single installation. This architecture is engineered for commercial battery storage applications where three-phase balance, high-efficiency transmission, and large-scale capacity are essential.
Best for: C&I EPC contractors, system integrators, industrial park developers, and microgrid projects.

LiFePO4 batteries — also known as lithium iron phosphate batteries — have become the dominant chemistry in stationary energy storage because of their thermal stability, long lifepo4 battery life, and consistent discharge performance. Unlike NMC chemistry, the phospho-olivine structure of LFP resists thermal runaway even under overcharge or mechanical stress, making it the preferred choice for installations in residential and commercial environments.
Every Rakour system is built with Grade A prismatic LiFePO4 batteries. The LV 200Ah Rackable Series is rated for ≥6,000 cycles; the LV 280Ah achieves ≥10,000 cycles; and the LV 314Ah and HV 314Ah flagship models reach ≥11,000 and ≥8,000 cycles respectively — all tested at 90% DOD. Operating temperature spans −20°C to 60°C for discharge, 0°C to 60°C for charging, covering virtually every global climate zone.
Unit) as the system master and a Slave BMS embedded in each module. The BCU aggregates real-time voltage, current, and temperature data from every module, performs system-level fault arbitrage, and executes coordinated charge/discharge management — a critical reliability advantage for large-capacity C&I deployments.

All Rakour battery storage products use Grade A LiFePO4 cells, operate within ≤85% RH humidity, support altitudes up to 2,000m, and carry a standard 5-year warranty. Communication ports — CAN, RS485, and RS232 — are standard across the LV lineup. The HV series adds built-in WiFi for wireless remote access without additional hardware.
Choose the LV Series when your project involves a single-family home, villa, or small off-grid installation requiring a 48V inverter ecosystem. Its plug-and-play rack module design means a two-person team can commission a full system in a few hours. The 15-unit parallel capability allows capacity to grow from 5.12kWh to 240kWh without replacing any hardware — a strong selling point for distributors targeting the home energy storage market and installers who need future-proofed solutions.
Choose the HV Series for three-phase commercial and industrial projects where load matching, demand charge reduction, or peak shaving are primary objectives. Higher system voltage reduces transmission current at equivalent power, lowering cable costs and improving round-trip efficiency. The BCU-managed architecture handles multi-module coordination automatically — simplifying commissioning on sites where 80kWh to 900kWh of capacity is required.
LV systems are designed for the 48V/51.2V hybrid inverter market. HV systems require high-voltage string or central inverters. Specifying the wrong series creates integration failure at commissioning. Rakour provides free project consultation to help integrators confirm the correct series before purchase — contact the technical team with your inverter model and load profile.
LiFePO4 chemistry's phospho-olivine bond structure is inherently more thermally stable than NMC or NCA alternatives. Even under abuse conditions — overcharge, short circuit, or external heat — Rakour's Grade A cells resist thermal runaway propagation, a property directly validated by the UN38.3 transport safety test that all Rakour products have passed.
Every Rakour system — LV and HV — is protected by an intelligent battery management system delivering eight real-time protections: overcharge, over-discharge, over-current, short circuit, high-temperature cutoff, low-temperature charging inhibit, cell voltage balancing, and SOC management. These protections operate at the module level on the LV Series and at both module and system level on the HV Series via the dual BCU/Slave BMS architecture.
The HV 314Ah model includes a built-in soft-start circuit, enabling compatibility with inverters that lack native soft-start functionality — preventing inrush current damage at system startup. Each HV battery module is also equipped with a dedicated cooling fan combined with a porous sheet-metal heatsink design, actively managing thermal load during high-power discharge cycles. IP20 protection is standard; outdoor cabinet configurations are available on selected HV models.
Rakour battery storage products are tested and certified to the major international standards required for market access across Europe and global export markets:
Distributors and EPC contractors can request the full certification package — CE Declaration of Conformity, UN38.3 test reports, MSDS sheets, IEC62619 certificates, product datasheets, and multi-language user manuals — directly from Rakour's commercial team. All documents are provided in English and are formatted for use in project tender submissions and customs clearance.
UL1973 and UL9540 certification pathways are on Rakour's active development roadmap for the HV Series. Partners targeting the North American market are encouraged to contact Rakour's business development team for current certification status and project feasibility assessment.
Rakour LV and HV systems communicate via CAN, RS485, and RS232 (LV Series), enabling direct BMS data exchange with the inverter's battery management interface. The LV 200/280/314Ah rackable models feature an onboard touchscreen color display that allows installers to switch communication protocols on-site without a laptop — a significant time-saving advantage during commissioning.
Rakour has published validated integration guides for the HV 314Ah Series with two Deye inverter models: the SUN-29.9K–50KSG01HP3 and the SUN-80KSG02HP3-EU-EM6. These guides cover power wiring (P1+/P1− to BAT1, P2+/P2− to BAT2), CAN communication line connection to the BMS1 port, and inverter parameter configuration for Lithium mode with parallel shunting — enabling a single battery stack to serve both inverter battery ports simultaneously to maximize output power while reducing system cost.
Beyond Deye, Rakour's CAN/RS485 protocol support is compatible with the battery inverter ecosystems of leading brands including Growatt, Solis, Goodwe, Luxpower, and SMA. Installers can request the official inverter compatibility list from Rakour's technical support team, specifying inverter brand and model to receive a pre-commissioning compatibility confirmation before placing an order.
The LV Series is designed around a battery expansion module architecture: each unit daisy-chains via communication cable to the next, with the first unit acting as the master BMS. No additional control hardware is required to add capacity. Starting at 5.12kWh with a single 100Ah module, an installer can reach 240kWh by paralleling 15 × 16kWh units — a flexibility that lets distributors offer customers a low entry cost with a clear upgrade path.
HV systems scale by adding battery modules in series (5 to 17 modules per stack) and by paralleling up to 4 complete stacks. The BCU automatically handles SOC balancing and charge/discharge coordination across all connected modules, eliminating the manual reconfiguration required by simpler architectures. The solar battery storage system approach — pairing Rakour HV with a high-voltage PV inverter — enables a single integrated system to handle generation, storage, and grid interaction with one communication backbone.
The LV NSTLV series supports wall-mount or wheeled floor-standing installation for space-constrained residential sites. The LV Rackable series uses standard 19-inch rack rails for data-center-style installations or outdoor battery cabinets. HV systems ship as pre-assembled iron-frame cabinets with alignment positioning holes, allowing two engineers to complete mechanical assembly before connecting power and communication lines. The HV 314Ah soft-start circuit further reduces installation complexity by eliminating the need to match inverter soft-start specifications.
The HV 200Ah and 314Ah series include an integrated WiFi module, enabling mobile app remote monitoring without additional hardware cost. Installers and end-users can view live SOC, module-level voltage, current, and temperature data from any location. The BCU aggregates data from all connected modules and pushes it via WiFi — giving system integrators a single monitoring endpoint for installations with multiple parallel HV stacks.
All LV Rackable 200/280/314Ah models feature an external touchscreen color display with dual indicator lights for charge status and power level. The screen presents real-time cell voltage, pack temperature, SOC percentage, and active protection events — allowing on-site engineers to diagnose system behavior without connecting a laptop or requesting remote access. This reduces service visit time and lowers after-sales support costs for distributors.
For system integrators building multi-asset energy management platforms, Rakour's CAN and RS485 ports expose standardized battery monitoring system data — SOC, SOH, voltage per cell, total current, and alarm codes — that can be ingested by third-party EMS and SCADA platforms. This open-protocol approach ensures Rakour batteries can be incorporated into virtual power plant (VPP) architectures and demand response programs without proprietary lock-in.
Rakour offers full OEM services for distributors and energy storage companies that want to bring a branded battery storage product to market quickly. On any standard LV or HV model, Rakour can apply your logo, customized color scheme, and branded packaging. We provide English, German, Spanish, French, and Portuguese user manuals for export markets. OEM orders use the same certified production line and test protocols as Rakour-branded units — your customers receive factory-certified performance under your brand identity.
For system integrators with specific technical requirements, Rakour's ODM program provides deeper customization: BMS communication protocol adaptation for proprietary inverter ecosystems, capacity and voltage configuration adjustments beyond the standard catalog, enclosure modifications for site-specific installation constraints, and custom BMS protection parameter tuning. Rakour's engineering team works directly with your technical leads to define specifications and manage production validation — from sample approval through mass delivery.
As a direct manufacturer — not a trading company — Rakour controls every stage of production: cell sorting, module assembly, BMS integration, and factory testing. This vertical control translates to consistent quality across batch deliveries, traceable production records for warranty claims, and competitive factory-direct pricing for distributors and EPC procurement teams. Minimum order quantities and lead times are discussed directly with the commercial team based on product and volume.
All Rakour LV and HV battery storage products carry a standard 5-year warranty covering manufacturing defects in cells, BMS hardware, and structural components under normal operating conditions as defined in the product user manual. The warranty is product-bound — it travels with the unit, not with the installer — so end-customers retain coverage regardless of the installing contractor's operational status.
Every Rakour product ships with a complete English-language documentation package: installation manual with wiring diagrams and BMS address configuration guide, technical datasheet, communication protocol reference, and troubleshooting FAQ. For distributors building local installer networks, Rakour provides training material packages — product specification presentations and installation procedure guides — to help your team deliver consistent, competent installations from day one.
Rakour's commercial team supports long-term partners with spare parts planning and priority technical response. BMS firmware updates are available to ensure ongoing inverter compatibility as inverter manufacturers push software updates. For integrators managing multi-site deployments, Rakour's remote diagnostics capability — via the HV Series WiFi module and CAN/RS485 data interfaces — enables fault identification without dispatching a field engineer, reducing battery storage operational costs across your installed base.
