SunReports is unique in this list, as it is an independent company, but it collects solar production data through a direct connection to SMA America, Kaco, Fronius, or PVPowered inverters. This avoids the hassle of installing alternating current transformers (CTs) into the breaker panel as required by most inverter-independent monitoring products (see “Inverter Independent Monitor” section). Its product can also monitor solar hot water systems. Data is collected by the Apollo1 unit and sent via Ethernet to the customer’s router. It can compare actual power generation against PVWatts or other software energy predictions.
