Built-in reverse charging automatically tops up the starter battery from the 48V bank when it's running low, and a dedicated Jump Start Assist mode can help get an engine started in an emergency without a separate jump pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specs:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInput: 12V (9-16V range), up to 115A\u003c\/li\u003e\n\u003cli\u003eOutput: 48V nominal (38-62VDC range), up to 26A\u003c\/li\u003e\n\u003cli\u003ePower Rating: approximately 1500W\u003c\/li\u003e\n\u003cli\u003eReverse Charging: sends ~40A back to the starter battery once the 48V bank exceeds 52.8V (54.0V for lithium)\u003c\/li\u003e\n\u003cli\u003eJump Start Assist: dedicated mode, 500W at 13.4V \/ 40A\u003c\/li\u003e\n\u003cli\u003eDimensions: 270 x 130 x 73mm\u003c\/li\u003e\n\u003cli\u003eWeight: 1.8kg\u003c\/li\u003e\n\u003cli\u003eWarranty: 5 years\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSized for larger 48V battery banks that need faster charging from a 12V vehicle electrical system than a 750W charger can deliver.\u003c\/p\u003e","brand":"Sterling Power","offers":[{"title":"Default Title","offer_id":47631049621694,"sku":null,"price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/0149\/8558\/files\/Sterling12Vto48V1500WChargerwreversechargingfeatureJump.webp?v=1784509743","url":"https:\/\/lightharvestsolar.com\/products\/sterling-12v-to-48v-1500w-charger-w-reverse-charging-feature-jump","provider":"LightHarvest Solar","version":"1.0","type":"link"}
