IP67 and an 80°C ceiling mean the charger can live under the floor, in a rear garage, or in a locker that takes road spray — which is often the only place left once the bank, inverter and fuse board have taken the cupboard. At 37.5mm deep it also fits behind panelling that will not take the 96mm 50A unit.\u003c\/p\u003e\u003ch3\u003eA 50V solar input is genuinely useful\u003c\/h3\u003e\u003cp\u003eWhere the compact 40A unit tops out at 30V, this accepts up to 50V, which means you can wire two 12V nominal panels in series without worrying about cold-morning open-circuit voltage. Series wiring keeps current down, so the cable from the roof can be thinner over a long run.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003e97% efficiency is high, but 50A still makes heat — the sealed case relies on conduction to whatever it is bolted to, so mount it to something metallic where you can.
