Frequently Asked Questions
Can this run my whole home, including AC?
It is designed for whole-home backup with 200A pass-through and 12kW of inverter output. Large central AC may need a soft starter, which your installer can advise on.
Does it work off-grid too?
Yes. The Sol-Ark 15K runs grid tied with battery backup, or fully off-grid with solar and generator support.
Who installs it?
A licensed electrician or solar installer. This is a permitted, panel-level installation, and the kit includes every major component they will need.
Is this genuine brand name equipment?
Yes. Renewable Outdoors is an authorized retailer for every brand in this kit, and each component carries its full manufacturer warranty.
Do you offer price matching?
Yes. If you find the same item advertised for less by another authorized dealer, reach out to us and we will do our best to match it.
