The EMP Hardened 15K passed 3rd party EMP conducted and radiated testing.


The Sol-Ark 15k Outdoor Case is a pre-wired system that contains the inverter, charge controller, and more, all in one package; no fuses, breakers, or combiner boxes necessary. With minimal additional hardware required, your install stays simple and low-cost.

Engineered, Serviced, And Tested In The USA

To back feed the output from this inverter to the grid, you'll need sufficient ampacity in your electrical system, which is most commonly satisfied by either:
• A 400A service panel 
• A supply-side tap with a 200A service.
• A 200A panel with a main breaker downgraded to 150A.

200A passthrough, so there’s no subpanel needed! This inverter is perfect for whole-home backup. Features and benefits include parallel stacking, grid sell, meter zero, time of use, smart load, AC coupling, & peak shaving.

Battery Agnostic
Sol-Ark inverters also do not have expensive battery restrictions like other solar inverters do, and can be used with a wide variety of 48V battery chemistries, from lead to lithium.

Highly Accelerated Life Testing
Proven to last well beyond the standard 10 year warranty

Install Simplicity
you don't have to piece together multiple parts to get basic functions. Theirs does it all, does it better, and does it with simplicity.

7 Day/Week Engineering & Customer Support
Sol-Ark beats all competition at customer support. The engineers assist with all questions, diagnoses, and remote unit management. They solve virtually any problem without a site visit

• Supports simultaneous DC and AC coupling. Boosts PV energy without increasing PV array size and reduces storage inverter costs.
• Comes with their award winning iron-clad 10 year warranty and their 7 day a week live 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: TBD 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!
