Panels can be added later on most hybrid inverters. At 50 kW it suits commercial and industrial installations. With about 80% of 57.32 kWh usable, a 1 kW evening load runs for roughly 45.9 hours before the battery needs a recharge (an estimate; real runtime depends on the load).<\/p>\n<h2>Key details<\/h2>\n<table class=\"spec-table\">\n<tbody>\n<tr>\n<th scope=\"row\">Inverter brand<\/th>\n<td>SAJ<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Inverter output<\/th>\n<td>50 kW<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Battery storage<\/th>\n<td>57.32 kWh<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Battery voltage class<\/th>\n<td>High voltage<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Package type<\/th>\n<td>Back-up<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">SKU<\/th>\n<td>SW-0250<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Before you order<\/h2>\n<ul>\n<li>Ask for the full component list: we send it with your quote so you can see exactly what is included and what installation material you still need.<\/li>\n<li>Tell us what has to stay on during an outage so we can confirm the inverter and battery size.<\/li>\n<li>Match the inverter to your supply: single phase for most homes, three phase for larger homes and businesses.<\/li>\n<li>Installation must be done by a registered electrician, who issues a Certificate of Compliance.
