With Sol-Ark’s remote access features and app you are never out of touch to quickly repair or adjust any system without being on site.

AC/DC Coupling

Supports simultaneous DC and AC coupling up to a combined 13kW of PV. Boosts PV energy 10-20% without increasing PV array size and reduces storage inverter costs up to 30%.

Warranty and Reliability

Comes with their award winning iron clad warranty and their 7 day a week live engineering support to assist you in all your needs.

Indirect Lightning, Solar Flare & EMP Hardening for Sol-Ark system.

Each EMP kit consists of the following three things:
1. One Box containing the inverter (already modified internally) and associated parts.
2. Large Suppressors: 40 count
3. Small Suppressors: 20 count

If the customer desires EMP battery backup – it's recommend
• Sol-Ark PCC230 (230Ah) batteries
• ANY 48V lead-acid / AGM battery

EMP hardening Sol-Ark inverters is an additional proprietary step in their manufacturing and production process. It is NOT a separate component. EMP hardening must be ordered when placing purchase orders.

Please make sure TWO(2) boxes are included:
• ONE inverter box
• ONE box containing suppressors

Important for the protection: Please be sure to check in with Sol-Ark’s Engineering Support when installing EMP hardened systems to ensure the suppressors are installed correctly per installation manual.

All EMP hardened systems come with suppressors!  EMP hardening the inverter alone will not protect the overall solar plus storage system setup, the suppressors must be installed!
