Before installing rooftop solar panels, many residential customers will be required to make expensive upgrades to their electrical service panel. These upgrades usually introduce delays and additional permitting requirements.
SDG&E® has created an alternative to installing these upgrades called the Renewable Meter Adapter (RMA). The RMA simplifies the interconnection process which may save time and money, making solar more affordable. SDG&E or an SDG&E Authorized Contractor will install both the RMA and the visible open fused disconnect. The RMA is installed between the electric meter and the electric service panel on the utility side. An internal breaker limits solar input to 48 amps maximum. The solar system connects to the visible open fused disconnect.
