Panels can be added later on most hybrid inverters. At 15 kW it suits small commercial sites, farms and large homes on a three-phase supply.<\/p>\n<h2>Key details<\/h2>\n<table class=\"spec-table\">\n<tbody>\n<tr>\n<th scope=\"row\">Inverter brand<\/th>\n<td>Solax<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Inverter output<\/th>\n<td>15 kW<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Phase<\/th>\n<td>Three phase<\/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-0553<\/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.
