String SP series inverter adopts low-frequency isolation transformer and is designed for small and medium photovoltaic power plants. It is ideal for solar generation in communication, telecommunication, petroleum, oceanography, meteorology, and so on. The capacities of this series are 3 Ks, 5 Ks, 6 Ks (outdoor type), 10 K, etc. The port adopts water-line terminals, which is easy to be connected and can be used in string. The 10 Ks is an indoor type, and can be used in parallel to simplify the design. String SP series will be your best choice.
