This is the Sol-Ark L3-HVR-60KWH, an outdoor-rated lithium iron phosphate (LiFePO4) battery cabinet built for commercial energy storage. It carries a nameplate capacity of 61.44 kWh DC and a usable capacity of 40.96 kWh DC at the recommended 90% depth of discharge. It is designed to pair with the Sol-Ark 30K-3P-208V inverter, with up to 6 battery units supported per inverter and up to 10 inverters allowed in parallel.

Field Notes: What This Battery Is Built For
Commercial and industrial installers spec the L3-HVR-60 series when they need outdoor-rated, high-voltage lithium storage that scales without a redesign. This is not a garage or RV battery — it is a 410V nominal, cabinet-format battery engineered to stack alongside Sol-Ark's 30K-3P-208V inverter platform. Sol-Ark states up to 6 battery units per inverter and up to 10 inverters in parallel, which is how a site scales from a single cabinet to a multi-megawatt-hour system. The chemistry is Lithium Iron Phosphate (LiFePO4), the same chemistry class prized in stationary storage for thermal stability and long cycle life compared to NMC lithium or lead-acid.
Battery Characteristics
Chemistry: Lithium Iron Phosphate (LiFePO4). Internal battery pack configuration is 8s1p. System nominal voltage is 410V DC, with an operating voltage window of 392V to 448V DC. This is a high-voltage commercial battery cabinet, not a 12V/24V/48V residential module — it is not interchangeable with low-voltage battery banks.
Wiring & Configuration Limits (Series/Parallel)
Per Sol-Ark's published data for this HV platform: up to 6 battery units are supported per compatible inverter, and up to 10 inverters can be run in parallel. Do not exceed the manufacturer's stated per-inverter battery count or inverter parallel count — doing so falls outside the documented configuration and can trigger BMS faults or void warranty coverage. This cabinet is NOT designed for series-stacking into a different nominal voltage class, and it is NOT a drop-in replacement for 48V residential battery racks.
Pro-Installer Tip
Charging is disabled below 0°C (32°F) per the battery's own BMS temperature protection, and output derates above 45°C (113°F). Repeated attempts to charge a cold-soaked lithium bank accelerate lithium plating on the anode, a failure mode that permanently reduces usable capacity and cannot be reversed by later warm-weather cycling. Before commissioning in cold climates, verify cabinet heater status (if equipped) and confirm state-of-charge with a shunt-based monitor rather than relying on inverter-displayed SOC alone — inverter estimates can lag actual cell voltage under load. Hold to the manufacturer's recommended 90% depth of discharge for daily cycling; this is the documented DoD for the stated 10-year / 196MWh throughput warranty, and cycling deeper on a routine basis is outside that warranty basis.
Key Benefits
- Outdoor IP55 (NEMA 3R) enclosure rated for freestanding installation without a separate weatherproof housing.
- 10-year or 196MWh throughput warranty, whichever comes first, at the manufacturer's stated end-of-life threshold of 70% retained capacity.
- 90% recommended depth of discharge with 94% round-trip efficiency (DC, 25°C, 0.5C) supports predictable usable-energy planning.
- Certified to UL1973, UL9540, UL9540a, and UN38.3, plus FCC and Prop 65 compliance — documentation commercial AHJs commonly require for permitting.
- Amphenol SurLok push-lock DC connectors standardize field wiring across cabinets.

Compatibility & Fitment
Positive fitment: This cabinet is documented for use with the Sol-Ark 30K-3P-208V inverter, supporting up to 6 battery units per inverter and up to 10 inverters in parallel for scaled commercial installations.
Negative fitment: This is NOT a residential 48V battery and is NOT interchangeable with Sol-Ark's low-voltage residential battery lineup. It is NOT rated for use as a starter or cranking battery. Charging is disabled below 0°C (32°F) by the BMS — standard lead-acid or non-lithium chargers are NOT recommended and are not compatible with this system's charge profile. Output is derated above 2000m altitude to a maximum of 0.8C; operation above 3000m is outside the stated altitude rating without contacting Sol-Ark directly.
