That turns a lunchtime stop at a site with electric into a real charging opportunity rather than a trickle — particularly valuable between November and February, when the roof contributes very little and driving is the only other option.\u003c\/p\u003e\u003ch3\u003eTwo limits to respect\u003c\/h3\u003e\u003cp\u003eFirst, your battery's maximum charge current: several packs cap at 100A or 150A across all sources, so 120A from the charger alone may exceed what the BMS will accept. Second, the site supply — 120A at 12V is roughly 1.5kW drawn from the bollard, so throttle it down on a 6A pitch.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eThe 8A transfer switch caps pass-through shore power at around 1.8kW, as on the 2,000W Pro. At 3,000W output the DC side pulls around 270A, so the battery cable and fuse need to be sized for that over a short run. 230V work should be certified by a qualified electrician.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":51358094655655,"sku":"RIV1230PCH-23S-UK","price":1109.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/1158\/3143\/files\/1_9b05b5db-3228-4968-92cc-9c68005e1227.jpg?v=1789800514","url":"https:\/\/shop.roamwired.com\/products\/renogy-3000w-pure-sine-wave-inverter-12v-to-230v-ups-backup","provider":"Roam Wired Shop","version":"1.0","type":"link"}
