What can this off-grid solar kit power?
It can support appropriately sized 120 V loads such as lighting, electronics and refrigeration. Check the combined running demand and appliance starting surges against both inverter and battery limits. This single-inverter package provides 120 V output.
How long will the battery last?
Runtime depends on usable battery energy, inverter losses and the loads you run. Solar production also varies with location, season, shade and panel orientation. Ask ROCKSOLAR to review your daily energy needs before choosing a system.
Can I connect it to the utility grid?
This is an off-grid inverter package. Alternate AC charging is different from exporting solar power to the utility grid. Discuss the correct system type with ROCKSOLAR if you need grid export or net metering.
Can I install it myself?
Experienced owners can participate in installation where permitted. The work you may perform depends on local requirements and your skills; arrange qualified electrical assistance and inspection as required.
