Frequently Asked Questions
What will 3kW run in a cabin?
Lights, a fridge, TV and devices, a small well or pressure pump, and tools one at a time. It is not sized for electric heat, a full-size electric range, or central AC.
Can I grow the system later?
Yes. The Growatt inverter is stackable for more output, and LifePower4 V2 batteries parallel for more storage.
Is the wiring included?
A basic PV wiring pack is included: 50ft of 10 AWG PV wire and MC4 connectors to wire the array to the inverter. Conduit, breakers, and permitting are site specific.
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.
