This is a Sol-Ark 15K-2P-LV hybrid solar inverter fitted with an EMP hardening kit, built for homeowners who want whole-home backup power and added protection against electromagnetic pulse events. It runs on a 48VDC battery bank and outputs standard 120/240VAC split-phase power for a home electrical panel.
The Sol-Ark 15K-2P-LV is a hybrid inverter: it operates grid-tied with battery backup, supports both DC and AC-coupled solar, and includes a 200A grid passthrough. It is not an off-grid-only unit, and it is not a chargeverter (it performs bidirectional inverter/charger functions, not AC-to-DC charging alone). 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.
- AC Output: 120/240V and 120/208V split-phase, 50/60 Hz

- Continuous AC Output: 13,000W at 240V / 11,260W at 208V
- Surge Output (10s): 24,000W at 240V / 20,800W at 208V - do not conflate this with continuous rated output
- Surge Output (30 min): 12,000W at 240V / 10,400W at 208V
- PV Input: 3x MPPT inputs, 150-425V operating range, up to 500V max input
- NOT compatible with 12V or 24V battery banks
- NOT an off-grid-only unit - designed for grid-interactive hybrid operation with NEM grid sell-back support
- 3-stage charge controller with equalization and CC/CV, BMS-controlled charging via CANbus/RS485/MODBUS RTU
- 5 ms backup transfer time keeps sensitive electronics running through grid outages
- CEC efficiency rated at 97.5%
- 200A grid passthrough helps avoid a main service panel upgrade on many retrofits
- Multifunction GEN port supports generator input, AC-coupled PV, or Smart Load management
- Supports both DC-coupled and AC-coupled solar PV in the same installation

FAQ
Can this inverter sell power back to the grid?
Yes. The Sol-Ark 15K-2P-LV supports NEM (net energy metering) grid sell-back where your utility interconnection agreement allows it. Confirm your local utility's interconnection rules before commissioning.
What battery voltage is required?
This inverter requires a 48VDC battery bank. It is NOT compatible with 12V or 24V battery systems.
Can I parallel multiple units together?
The unit includes parallel RJ45 communication ports for multi-unit stacking. Exact maximum stacking count is [NEEDS VERIFICATION] - refer to the manufacturer datasheet in the Resources tab.
Is this UL 1741 listed for utility interconnection?
Specific UL 1741 listing status is [NEEDS VERIFICATION] in the provided manufacturer data. The datasheet references multiple UL 9540 certifications at the system level (battery plus inverter combination), which is a separate listing from a standalone inverter's interconnection certification.
Does this include EMP protection?
Yes, this SKU (SA-15K-EMPKIT) bundles the 15K-2P-LV hybrid inverter with an EMP hardening kit. Specific EMP shielding specifications and test standards are [NEEDS VERIFICATION] - refer to the manufacturer datasheet.
Warranty & Registration: Manufacturer warranty term and coverage details were not present in the provided manufacturer data - [NEEDS VERIFICATION]. Register your unit through the MySolArk platform referenced by the manufacturer, and refer to the "Resources (System Manuals and Warranty)" Tab above for the official warranty document.
