The Sol-Ark SA-30K-3P is a 30,000 W commercial hybrid inverter built for 208VAC 3-phase service. It accepts a high-voltage DC battery input (160-500V range) and is designed for light commercial and institutional sites — schools, municipal buildings, and similar facilities that need backup power and PV/battery integration.

Field Notes
This is an inverter, not a standalone battery. It is compatible with lithium-ion battery systems within its stated DC input range, but the battery pack itself — cells, BMS, enclosure, cabling — is sold separately and is not part of this SKU. If you are shopping for a self-contained deep-cycle battery (golf cart, RV, marine, or home off-grid storage), this listing is not that product; it is the power-conversion hardware that a compatible battery connects to.
Battery Chemistry [NEEDS VERIFICATION FOR SPECIFIC PACK]
The inverter accepts lithium-ion battery banks. DATA does not specify a chemistry sub-type (e.g., LiFePO4 vs. NMC) for any bundled battery, because no battery pack is included with this SKU. Battery chemistry compatibility must be confirmed against Sol-Ark's published compatible-battery list before purchase — [NEEDS VERIFICATION].
DC Input / Battery Interface Characteristics
Nominal DC bus voltage is 300 V, with an operating voltage window of 160-500 V. The unit supports a total battery capacity range of 50-9900 Ah across up to 2 battery inputs, each rated at 50 A (100 A combined). Charge/discharge control is CC/CV, BMS-controlled, with CAN (Controller Area Network) communication required for active BMS reporting.
Wiring & Configuration Limits
The SA-30K-3P has 2 battery input channels, each rated for 50 A, for a combined 100 A charge/discharge current at the inverter. Up to 10 inverter units can be paralleled at the system level. Battery bank sizing must land within the 160-500 V operating window and the 50-9900 Ah capacity range stated by the manufacturer.
NOT included: No battery cells, modules, or racks ship with this SKU. NOT compatible with battery packs lacking active CAN-based BMS communication — active BMS communication is required for all lithium batteries on this inverter. Do not connect a battery pack outside the 160-500 V range; this can trigger inverter faults or damage.
Pro-Installer Tip
Mismatched battery voltage windows are the most common commissioning error on 3-phase commercial inverters like this one. If a battery bank's resting voltage falls outside the 160-500 V operating range, the inverter will not charge it correctly, and repeated attempts to force a charge outside that window accelerate cell imbalance across the pack. Prevent this by verifying pack voltage and CAN/BMS handshake with a multimeter and the battery manufacturer's BMS diagnostic tool before energizing the AC side. For lithium battery banks paired with this inverter, keep depth of discharge within the range specified by the battery manufacturer — typically 80-100% DoD for LiFePO4 packs — rather than relying on inverter-side assumptions alone.

Compatibility & Fitment
This inverter is compatible with lithium-ion battery banks operating within 160-500 V DC and 50-9900 Ah, provided the battery has active CAN-based BMS communication. It is NOT compatible with battery packs that lack BMS communication over CAN. It is NOT a standalone battery product — no cells, battery modules, or racks are included. It requires a 208VAC 3-phase electrical service; it is NOT designed for single-phase 120/240V residential service. Grid-to-battery charging and battery discharge are both BMS-controlled; standard, non-communicating lead-acid chargers are NOT applicable to this system's lithium battery charge path.

FAQ
Does this listing include a battery?
No. This SKU is the inverter only. It accepts a compatible lithium-ion battery bank within the 160-500 V, 50-9900 Ah range, but the battery itself is sold separately.
What voltage and phase does this inverter output?
120/208 V AC, 3-phase, at 50/60 Hz, with a real power rating of 45,000 VA continuous.
Can I connect a lead-acid battery bank instead of lithium?
DATA specifies lithium-ion, stackable battery chemistry for the battery input. Compatibility with lead-acid chemistries is not confirmed in the manufacturer specifications provided — [NEEDS VERIFICATION].
How many of these inverters can be paralleled together?
Up to 10 units can be paralleled, allowing the system to scale from 30 kW up to 300 kW.
What is the operating temperature range?
-40 C to 60 C, with power derating above 45 C.
