On Sept. 1, RVIA began mandatory enforcement of new standards for electrical components, including the 2026 edition of NFPA 1192, the 2025 ANSI/RVIA DC Standard, and adopted portions of the 2026 National Electrical Code. Article 551.40(D) on grounding-monitor interrupters was excluded pending availability of listed devices. RVIA enforces through more than 2,000 unannounced inspections of member-company RV manufacturing plants annually. Section 2-7 of the DC standard requires that an RV shipping with solar installed carry a charge controller listed by a nationally recognized testing laboratory and rated for the array it feeds. Renogy’s REGO MPPT charge controllers, in 30A and 60A, publish certification to UL 1741 alongside CAN/CSA-C22.2 No. 107.1 and IEC 62109. For service departments, the rule means that if panels are touched, the charge controller must be examined, as a change in array wattage or configuration can exceed the installed controller’s rating.
