Installed and wired, with nothing left to buy
Many sellers hand you an inverter and a battery and leave the rest to you: find an electrician, buy cable and breakers, and hope whoever wires it understands the system. We do it differently. The price covers the equipment, the cables and the installation, and our own technicians fit it.
Standard installation is included in the price. If your site needs extra work, such as unusually long cable runs or additional mounting, we tell you what is involved and what it costs before anything starts.
