RSA 362-A:10, IV: one system per metered customer with a MAXIMUM INVERTER OUTPUT of 1,200 watts AC. The utility may not require approval, an interconnection review or agreement, a fee, or extra equipment - but 362-A:10, II lets it develop a method for the customer to report the system's wattage AFTER installation, for notification purposes only. 362-A:10, V requires the Department of Energy to publish notice that connecting an unlisted system, or one installed contrary to the state building code or manufacturer instructions, MAY AFFECT HOMEOWNERS OR RENTERS INSURANCE COVERAGE.
