This is a 60kW commercial hybrid inverter built for three-phase 480/277VAC facilities running on lithium-ion battery storage. It is not a battery itself — it is the DC-to-AC conversion and battery-charging hub that a high-voltage lithium battery bank connects to. If you are sourcing this for a commercial or industrial site with a 600V nominal DC battery bus, this page covers the electrical limits you need to size the system correctly.
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.
Why This Matters in the Field
A 60kW inverter of this class is typically deployed in commercial and industrial settings — distilleries, ranches, schools — where a lithium battery bank needs to deliver real backup hours, not just a few minutes of ride-through. The manufacturer's own case studies show this inverter paired with 60kWh and 120kWh lithium storage systems providing 12-14 hours of continuous backup. Sizing your battery bank against this inverter's DC input limits is the single most common mistake we see on commercial installs — get the voltage window and current draw wrong, and you either trip the BMS or leave capacity on the table.
Battery Chemistry & Configuration
This inverter is designed exclusively for lithium-ion battery chemistry on its DC input. It is not rated for lead-acid, AGM, gel, or flooded battery banks. The battery bus operates at a nominal 600VDC, with an accepted operating range of 160V to 700V. Total battery capacity across the system can range from 50Ah to 9900Ah, giving you wide latitude in bank sizing as long as the voltage and current limits below are respected.
Wiring & Configuration Limits
The unit has two battery input channels, each rated at 50A, for a combined maximum battery charge/discharge current of 100A. Do not exceed 50A on either individual input — this is a hardware terminal rating, not a soft limit. The inverter itself can be stacked up to 10 units in parallel for larger commercial installations. Active BMS communication over CAN bus is required for all connected lithium batteries; this inverter will not manage an unmonitored or "dumb" lithium bank safely. Only batteries on Sol-Ark's published compatibility list should be paired with this inverter — check solark.com before finalizing a battery order.
Pro-Installer Tip
The most common failure mode on high-voltage commercial lithium installs is exceeding the 50A per-input terminal rating during simultaneous multi-battery discharge events, which causes nuisance BMS lockouts and accelerated terminal wear. Staying within the 100A combined / 50A per-input ceiling prevents this lockout cycle and protects the battery's own internal BMS from repeated hard cutoffs, which shorten cell life over time. Verify actual current draw per input with a CAN-bus-integrated monitoring platform (MySolArk) rather than assuming even load-sharing across both inputs. As a professional standard, size your lithium bank so that sustained commercial loads keep depth of discharge in the 80-100% DoD range the chemistry supports, while leaving headroom below the 100A combined ceiling for inrush and generator-assist charging events.

Compatibility & Fitment
This inverter is compatible with lithium-ion battery banks operating within the 160-700V DC range, using active CAN bus BMS communication, from Sol-Ark's published compatible battery list. It supports AC coupling with existing grid-tied PV systems and can be stacked up to 10 units in parallel for larger system capacity.
It is NOT compatible with lead-acid, AGM, gel, or flooded battery banks. It is NOT compatible with batteries lacking active CAN bus BMS communication — passive or non-communicating lithium batteries are not supported. It is NOT rated for delta systems with corner-grounding, high-leg delta, or 240V delta configurations. Standard lead-acid chargers are NOT applicable to this DC-coupled battery input; charging is managed entirely through the inverter's integrated CC/CV BMS-controlled charge stage.
