SMARTWATT ECO – a series of backup inverters act as an uninterruptible power supply with the ability to charge batteries from the sun. These inverters are designed for 1 and 3 kW in power, they have the ability to connect solar panels up to 500 – 1200 Watt and batteries with voltage up to 12 – 24 Volts, depending on the inverter model. Such inverters are used in small solar stations where reliability, ease of use and installation are required. In models with a power of 1 kW, the input from the network is implemented in the form of a standard socket, while the output from the inverter is implemented in the form of a universal terminal block. In 3 kW models, the inverter input and output are implemented in the form of a terminal block.
