Frequently-Asked Questions

What is the difference between the EG4 6000XP and 12000XP?

The 6000XP is a 6kW inverter ideal for medium homes or partial backup. The 12000XP is a 12kW inverter suited for full-home systems and larger arrays.

Can I expand my battery capacity later?

Yes. Start with one battery and add a second later; you’ll need the correct conduit boxes and paralleling cable when expanding.

Can I start without solar panels and add them later?

Yes. The kit can operate without solar panels initially and can be expanded with panels when ready.

Do I need professional installation?

Yes. For safety and warranty protection, installation by a licensed electrician or solar professional is strongly recommended.

Can I upgrade from the 6000XP to the 12000XP later?

Yes, the system is designed to be scalable. You can upgrade to the larger inverter when your energy needs grow.
