This is the Sol-Ark L3-HV-60KWH, a lithium iron phosphate (LiFePO4) commercial battery energy storage system built for indoor installation. It is part of the Sol-Ark L3 Series lineup, which shares core cell chemistry and BMS architecture across several cabinet sizes. Sol-Ark's published datasheet excerpt in our source data lists detailed specifications under model names L3-HVR-60KWH (outdoor) and L3-HV-40KWH (indoor), so several field values below are marked [NEEDS VERIFICATION] where we could not confirm they apply directly to the 60 kWh indoor cabinet (L3-HV-60KWH) rather than a neighboring model in the same series.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate). The L3 Series is built as a stacked commercial energy storage cabinet, not a single-cell battery — Sol-Ark's own literature describes it as a modular system of battery packs designed for indoor or outdoor deployment. The specific L3-HV-60KWH indoor SKU requested here does not have a fully isolated spec row in the manufacturer text we were given; the closest confirmed indoor spec set in the source belongs to the L3-HV-40KWH cabinet, and the closest 60 kWh-class spec set belongs to the L3-HVR-60KWH outdoor cabinet. Treat capacity, power, and dimension figures below with that caveat in mind. [NEEDS VERIFICATION]
Confirmed series-wide facts: cell chemistry is Lithium Iron Phosphate. Battery pack internal configuration is 8s1p. Individual battery module nominal capacity is 5.12 kWh at 51.2V / 100Ah. Recommended Depth of Discharge across the L3 Series is 90%. Roundtrip efficiency (DC charge/discharge) is 94% at 25C, 0.5C rate.
Wiring & Configuration Limits (Series/Parallel)
System nominal DC voltage for the HV platform is 410V, with an operating voltage window of 392V to 448V. Internal battery pack configuration is 8s1p per module. The L3 HVR-60 platform can stack up to 6 inverters and 36 battery cabinets in the full commercial build-out (180 kWac / 2.2 MWh); the L3 HV-40 platform can stack up to 10 inverters and 160 battery cabinets (300 kWac / 6.4 MWh). Max battery units per inverter and max inverters in parallel for the HV-40 configuration are listed as 16 and 6s6p respectively in the source table — confirm which stacking limit set applies to L3-HV-60KWH specifically before designing a multi-cabinet system. [NEEDS VERIFICATION]
This is a commercial three-phase battery energy storage cabinet. It is NOT a drop-in 12V/24V/48V lithium battery, and it is NOT wired using simple series/parallel golf-cart or RV conventions — configuration is managed through the compatible Sol-Ark inverter platform and Sol-Ark engineering guidance. Do NOT attempt to integrate this cabinet with non-Sol-Ark inverters unless explicitly cleared by Sol-Ark technical sales.
Pro-Installer Tip
Commercial LiFePO4 cabinets like this one are unforgiving of charging below freezing: the BMS disables charging below 0C (32F), and repeated attempts to push current into cold cells accelerates lithium plating and permanent capacity loss long before the rated cycle life is reached. Confirm the cabinet's internal temperature — not just ambient jobsite temperature — before energizing charge circuits in cold climates, and use a monitoring platform with cell-group temperature reporting (a shunt-based or BMS-integrated monitor, not a generic voltmeter) to verify the pack is above threshold. On a system engineered around a 90% recommended depth of discharge, treat that DoD ceiling as a design limit, not a target to exceed on every cycle — running consistently to the edge of DoD shortens the 10-year/throughput-based warranty window faster than moderate cycling.
Key Benefits
- LiFePO4 chemistry with 90% recommended depth of discharge, rated for 10 years or MWh-based throughput warranty coverage depending on cabinet model.
- 94% roundtrip DC efficiency (25C, 0.5C) reduces energy loss across daily charge/discharge cycles.
- Modular battery module design (5.12 kWh per module, 51.2V/100Ah) supports scalable commercial stacking.
- Built-in DC disconnect and internal fusing (200A disconnect rating referenced in the L3 platform table) for system protection.
- UL1973, UL9540, UL9540a, and UN38.3 certifications support field and code-compliance documentation.

Compatibility & Fitment
This cabinet is designed to pair with compatible Sol-Ark commercial inverter platforms as part of the L3 Series ecosystem. It is NOT compatible with generic residential lithium chargers, standard lead-acid chargers, or third-party inverters outside the Sol-Ark-approved platform — standard lead-acid chargers are NOT recommended for this system under any circumstance. It is NOT a starter battery and is NOT designed for automotive or marine cranking applications. Charging is disabled by the BMS below 0C (32F); do not attempt to force-charge the system in sub-freezing conditions. Confirm exact inverter model compatibility and maximum stacking configuration for the L3-HV-60KWH SKU with Sol-Ark technical sales or MSSD before finalizing a multi-cabinet system design, since the source documentation available to us covers the HVR-60 (outdoor) and HV-40 (indoor) SKUs directly rather than HV-60KWH indoor by name.
FAQ
Q: What battery chemistry does the Sol-Ark L3-HV-60KWH use?
A: Lithium Iron Phosphate (LiFePO4).
Q: Can this system charge in freezing temperatures?
A: No. The BMS disables charging below 0C (32F). Derating also occurs above 45C (113F) per the L3 Series datasheet.
Q: Is this an indoor or outdoor rated enclosure?
A: This SKU is sold as the indoor configuration. Indoor L3 cabinets in the manufacturer documentation carry an IP20 (NEMA 1) ingress rating, versus IP55 (NEMA 3R) for outdoor L3 cabinets.
Q: Can I mix this battery with a different inverter brand?
A: Not without confirmation from Sol-Ark. This is a commercial three-phase system designed around Sol-Ark's L3 Series inverter platform, and cross-brand pairing is not documented in the source specifications.
Q: What is the recommended depth of discharge?
A: 90%, per Sol-Ark's L3 Series datasheet.
Warranty & Support
Sol-Ark's L3 Series documentation lists a product warranty of 10 years, with performance warranty defined by either 10 years or a throughput ceiling (196 MWh for the HVR-60 cabinet, 130 MWh for the HV-40 cabinet) to end-of-life at 70% retained capacity. Confirm the exact warranty terms tied to the L3-HV-60KWH SKU using the manufacturer documentation tab before purchase. Ask us before you order if you are unsure which cabinet configuration or stacking limit applies to your system design — we always reply back.
