High Voltage Battery Storage
BSLBATT high voltage battery storage systems are engineered for three-phase inverters, large residential installations, and commercial energy storage applications. Operating between 100V and 800V DC, HV LiFePO4 battery systems deliver higher DC efficiency, reduced cable losses, and scalable capacity from 15kWh to over 300kWh per installation.
All HV models use cobalt-free LiFePO4 cells. The stable cathode structure eliminates oxygen release under thermal stress, making high voltage lithium battery installations safe for indoor and outdoor enclosures without active fire suppression.
HV battery systems operating above 300V DC reduce current at equivalent power output, lowering resistive losses across DC cabling and improving overall round-trip efficiency compared to low-voltage alternatives.
HV battery systems communicate via CAN BUS and Modbus RTU, compatible with three-phase inverters from Victron Energy, Deye, Goodwe, SolaX, SMA, Schneider Electric, and 20+ additional manufacturers.
Stackable HV architecture allows capacity to be configured at the point of installation. Systems scale from 15kWh entry configurations to 300kWh+ multi-rack deployments without redesigning the battery interface.
MatchBox HVS series carries IP65 rating for dust and water ingress protection. Suitable for outdoor installation in exposed environments across climates from −10°C to 55°C discharge operating range.
Certifications across the HV range include CE, IEC 62619, IEC 62040, IEC 62477, and CEC Listed, covering requirements for Europe, Australia, and major export markets. UN38.3 and MSDS documentation available for all models.

FAQ
What voltage do high voltage battery storage systems operate at?
BSLBATT HV battery systems operate between 100V and 800V DC depending on model and configuration. The MatchBox HVS series covers 307V to 717V across 3 to 7 module configurations. ESS-GRID series extends to higher voltages for commercial and industrial applications.
What inverters are compatible with high voltage battery storage?
HV battery systems communicate via CAN BUS and Modbus RTU. Compatible three-phase inverter brands include Victron Energy, Deye, Goodwe, SolaX, SMA, Schneider Electric, Growatt, and 20+ additional manufacturers. Compatibility depends on inverter DC input voltage range matching the battery system output voltage.
What is the difference between HV and LV battery storage?
LV systems operate at 48–51.2V and suit single-phase residential installations up to 20kWh. HV systems operate above 100V DC, pair with three-phase inverters, and are suited to larger installations where higher DC voltage reduces cable current and improves system efficiency.
How scalable are high voltage battery systems?
HV systems scale by adding modules within a rack or adding parallel racks. BSLBATT HV systems support multi-rack parallel configurations covering capacities from 15kWh to over 300kWh per installation without redesigning the battery interface.
What certifications do BSLBATT high voltage batteries carry?
Certifications across the HV range include CE, IEC 62619, IEC 62040, IEC 62477, and CEC Listed. UN38.3 and MSDS documentation are available for all models. Specific certification coverage varies by model.
Can high voltage battery storage be used off-grid?
Yes. HV battery systems support off-grid configurations when paired with compatible high-voltage inverter-chargers. Stable high-voltage DC output makes HV storage well-suited to off-grid microgrids and large standalone power systems.
