At 16kWh in a high-voltage (400V) architecture, it delivers meaningful backup runtime for whole-home essential loads without the oversized footprint of lower-voltage alternatives. LG's high-voltage design reduces current draw at the battery level — lower heat generation, longer cycle life, and better efficiency under continuous load. If you're backing up an EV charger, HVAC, or medical equipment, that matters more than peak kWh numbers. Compatible with leading inverters including Growatt, SolarEdge, SMA, and others. Two units can be paralleled for 32kWh total.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cpd-acc-item\"\u003e\n\u003cbutton class=\"cpd-acc-trigger\" onclick=\"cpdT('cpd-product-8763780628633',this)\"\u003eSpecifications \u003cspan class=\"cpd-acc-icon\"\u003e+\u003c\/span\u003e\u003c\/button\u003e\u003cdiv class=\"cpd-acc-body\"\u003e\u003ctable class=\"cpd-specs\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eUsable Capacity\u003c\/td\u003e\n\u003ctd\u003e16kWh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Chemistry\u003c\/td\u003e\n\u003ctd\u003eLiFePO4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e400V (high voltage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth of Discharge\u003c\/td\u003e\n\u003ctd\u003e95%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRound-Trip Efficiency\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;95%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCycle Life\u003c\/td\u003e\n\u003ctd\u003e6,000 cycles @ 80% capacity retention\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e14°F to 113°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e220 lbs (100 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eWall-mounted, IP55 (indoor\/outdoor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScalability\u003c\/td\u003e\n\u003ctd\u003eUp to 2 units in parallel (32kWh total)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eUL 9540, UL 9540A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e10 years (LG Energy Solution)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cpd-acc-item\"\u003e\n\u003cbutton class=\"cpd-acc-trigger\" onclick=\"cpdT('cpd-product-8763780628633',this)\"\u003eWhat's Included \u0026amp; What You'll Need \u003cspan class=\"cpd-acc-icon\"\u003e+\u003c\/span\u003e\u003c\/button\u003e\u003cdiv class=\"cpd-acc-body\"\u003e\n\u003cp\u003e\u003cstrong style=\"color:#191970\"\u003eShips with:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin:8px 0 16px 20px\"\u003e\n\u003cli\u003eLG RESU16H Prime battery module\u003c\/li\u003e\n\u003cli\u003eWall mounting bracket and hardware\u003c\/li\u003e\n\u003cli\u003eCommunication cables\u003c\/li\u003e\n\u003cli\u003eInstallation manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong style=\"color:#191970\"\u003eWhat you'll need (not included):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin:8px 0 16px 20px\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible hybrid inverter\u003c\/strong\u003e — the RESU16H Prime does not operate without one\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLicensed electrician\u003c\/strong\u003e — high-voltage battery installation requires a licensed professional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical permit\u003c\/strong\u003e — required for battery storage in most U.S. states\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad calculation\u003c\/strong\u003e — confirm which circuits you want backed up and that your inverter can handle them\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"font-size:14px;color:#666\"\u003eBudget $1,500–$3,500 for installation depending on system complexity and location.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cpd-acc-item\"\u003e\n\u003cbutton class=\"cpd-acc-trigger\" onclick=\"cpdT('cpd-product-8763780628633',this)\"\u003eShipping \u0026amp; Returns \u003cspan class=\"cpd-acc-icon\"\u003e+\u003c\/span\u003e\u003c\/button\u003e\u003cdiv class=\"cpd-acc-body\"\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Free freight shipping to all 48 continental U.S. states.
