Inverter STECA GRID 300

StecaGrid inverters are designed for use in solar photovoltaic systems, working in parallel with the central power supply network. The inverter converts the data obtained from the solar modules into alternating direct current and pass it on to the consumers connected to the electricity network.

Warning!
Despite the fact that the inverter is protected against power supply to the network when disconnected mains voltage (for example, during repair work on power lines), for the supply of energy to the network is necessary to permit the power supply organization. Without such permission the user has to ensure that the consumption of all the electricity generated by solar panels, local electrical load at any time.

The inverter StecaGrid 300 is ideal for small solar power systems ranging from 300 watts to 3600 watts. The increase in power is possible when connecting multiple inverters in one system. High efficiency (95.8%) and ease of use is achieved by having each of the inverter system independent device tracking the point of maximum power output generated by the charge source (principle independent circuit)
