Combining them saves a run, saves a fuse pair, and — more usefully — means one device is arbitrating between the two sources rather than two devices both trying to hold the bus voltage.\u003c\/p\u003e\u003ch3\u003eWhere 30A lands\u003c\/h3\u003e\u003cp\u003e30A suits a 100–200Ah bank. Below that you are over-specified; much above it and a day's driving stops making a meaningful dent, at which point the 50A is the better buy. Terminals take 8AWG to 4AWG, which is the right range for a typical cab-to-habitation run.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eFusing is specified at 75–100A on both input and output — heavier than the 20A unit, so plan the cable accordingly. The wide −35°C to 65°C operating range means it is happy in an unheated locker even if the battery it feeds is not.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":51358082990247,"sku":"RBC30D1S-BT-UK","price":169.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/1158\/3143\/files\/59760_source_1702888348__79693.1745566896.1280.1280.jpg?v=1789800304","url":"https:\/\/shop.roamwired.com\/products\/renogy-dcc30s-12v-30a-dual-input-dc-dc-on-board-battery-charger-with-mppt","provider":"Roam Wired Shop","version":"1.0","type":"link"}
