The GoodWe 5kW inverter is a great light weight and simple inverter that comes with the industry standard 10 year warranty. It can be overloaded with solar panels to a maximum of 6.66 kW to ensure that it is feeding your meter box with 5 kW of steady power for a greater portion of the day. It is IP65 rated for indoor or outdoor installation and uses a heat-sink for cooling as opposed to a fan so has increased reliability over inverters with older technology. It can be linked to your WiFi system for power monitoring. In the field, this is one of the most reliable inverters on the market.
