Thinking of plug-in solar? Your RCD may not be safe for it.
Plug-in solar feeds electricity back into your wiring. Older Type AC RCDs can be damaged or blinded by reverse current, so they may not trip when you need them.
Duffett Electrical will inspect your consumer unit for free, no obligation. If an upgrade is needed, we’ll quote for bidirectional RCDs and plug-in solar where the home is suitable.
One system per home. Wall socket only, never an extension lead. Not every home is compatible.
Weymouth, Dorchester, Portland, Bridport and nearby.
