The SPF 12000T DVM-US solves that with true 48V split-phase 120\/240V output, which means your off-grid home runs on the same electrical standard as every other house in America.

Large appliances — electric ranges, dryers, well pumps, central HVAC, EV chargers — require 240V. A 120V-only off-grid inverter means those appliances simply won't run. The SPF 12000T's split-phase output lets your off-grid home use standard US wiring and appliances without modification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow large a battery bank does a 12kW off-grid inverter need?\u003c\/strong\u003e\u003cbr\u003eIt depends on your daily load and how many hours of autonomy you want. A rough starting point: if your home uses 30–40kWh per day and you want 1–2 days of autonomy, you need 30–80kWh of usable battery capacity. Use our Build Your System guide to calculate your specific requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used with a generator as the primary backup?\u003c\/strong\u003e\u003cbr\u003eYes — the built-in generator input allows the inverter to accept AC power from a generator to charge batteries and power loads when solar production is insufficient. This is a common off-grid configuration for winter months or extended cloudy periods.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this suitable for a new off-grid construction or a cabin retrofit?\u003c\/strong\u003e\u003cbr\u003eBoth. New off-grid construction can be wired around the split-phase output from the start. Existing cabins with 120V wiring can run on one leg of the split-phase output while 240V circuits are added as needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"background:linear-gradient(135deg,#191970,#0d0d4a)!important;border-radius:10px!important;padding:28px!important;margin:28px 0 0!important;text-align:center!important\"\u003e\n\u003cp style=\"font-family:'Montserrat',sans-serif!important;font-weight:800!important;font-size:16px!important;color:#fff!important;margin:0 0 6px!important\"\u003eBuilding or expanding a backup system?\u003c\/p\u003e\n\u003cp style=\"font-size:14px!important;color:rgba(255,255,255,0.8)!important;margin:0 0 18px!important\"\u003eUse our Build Your System guide to size your inverter, battery bank, and solar array before you order.\u003c\/p\u003e\n\u003ca href=\"\/pages\/build-your-system\" style=\"display:inline-block!important;background:#7DF9FF!important;color:#191970!important;font-family:'Montserrat',sans-serif!important;font-weight:800!important;font-size:14px!important;text-transform:uppercase!important;letter-spacing:1px!important;padding:14px 32px!important;border-radius:6px!important;text-decoration:none!important\"\u003eBuild Your System →\u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003cscript\u003efunction cpdT(id,btn){var b=btn.nextElementSibling;var o=b.classList.contains('open');var w=document.getElementById(id);w.querySelectorAll('.cpd-acc-body').forEach(function(x){x.classList.remove('open')});w.querySelectorAll('.cpd-acc-trigger').forEach(function(x){x.classList.remove('open')});if(!o){b.classList.add('open');btn.classList.add('open')}}\u003c\/script\u003e\n\u003c\/div\u003e","brand":"Growatt","offers":[{"title":"Default Title","offer_id":47851471208601,"sku":"82616451192115","price":2399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/4944\/1433\/files\/Growatt_12KW__83617.jpg?v=1779714013","url":"https:\/\/chargeprodirect.com\/products\/growatt-12kw-split-phase-off-grid-inverter-ul-1741-certified-spf-12000t-dvm-us-mpv","provider":"Charge Pro Direct","version":"1.0","type":"link"}
