Sol-Ark 15K All-In-One Hybrid Solar Battery System

1 – 4 $8,250.00 $0.55
5 + $7,758.31 $0.52

Note: Sol-Ark estimates CEC Certification will be available in September 2022.

Available: 3


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

Sol-Ark is shipping the 15K with full UL certifications, but there will be an estimated delay for the California, Hawaii, and Canada markets as additional local certifications and compliance need to be obtained. EMP-resistant units are not available for preorder but should be available around Q4 2022, pending testing availability. 

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
