What still needs checking

Identify your microinverter generation before confirming a 5P retrofit.
Confirm the gateway/combiner, metering and wired communications.
Outage backup needs a compatible grid-isolation controller and electrical design. Battery storage alone does not provide outage backup.
Motor starting, voltage and actual nameplate ratings need verification, especially for AC, pumps and refrigeration.
Site wiring, service capacity, mounting, permits, utility requirements and final commissioning need an installer review.
