Professional System Design Required
A qualified solar or electrical professional must confirm panel string sizing, inverter input limits, battery configuration, load requirements, racking, wiring and required protection equipment. Grid-connected installations require applicable permitting and utility approval. Actual solar production, usable battery energy and supported loads depend on location, weather, system settings and operating conditions.
Frequently Asked Questions
Can this kit be connected to the utility grid? +
Yes, the kit can be designed for grid-connected operation. Your installer must confirm equipment approvals, local permitting requirements and utility interconnection approval.
Will it provide power during an outage? +
Yes, when properly designed, installed and configured for backup operation. Supported loads depend on inverter capacity, battery charge, available solar production and the property's electrical design.
Is the system output 16.38kW? +
16.38kW is the combined rated DC capacity of the 36 solar panels. The Envy Duo 21 provides up to 12kW of continuous backup output, subject to operating conditions. Its maximum PV-powered AC output is 16kW at 240V or 13.8kW at 208V.
How much energy does the battery store? +
The two eForce battery modules provide 19.2kWh of nominal storage. Usable energy depends on reserve settings, operating conditions and system losses.
How long will the battery power my home? +
Runtime depends on the loads being powered. Lighting, refrigeration and electronics use less energy than electric heating, central air conditioning and other large appliances. A load analysis helps determine the right backup configuration for your home.
