Parallel Inverter, Off-grid Inverter - Apollo STP-210p, Bidirectional Inverter


Three Phase Bidirectional Parallel Inverter

Brochure   Inquiry  
APOLLO STP-210p series is stand-alone three phase bidirectional parallel inverter with capability to parallel output to expand power or increase reliability of PV system. It can be connected up to 8 inverters in parallel. Parallel inverter system are designed to have the advantage to increase output power and enhance reliability. It converts the DC power from battery into AC power to supply AC appliances. It can operates with solar charge controller in order to utilize solar energy or charge battery and also can operate with diesel genarator for charging batterty,too. This inverter operate in multi-master operation scheme thus there is not master unit and no external controller in system, each inverter equipped with microprocessor that makes it high performance and efficiency. This parallel inverter is suitable from stand-alone solar power system in remote area where reliability is important.
APOLLO STP-210p series inverter can install the optional battery/PV ground fault detection circuit board for detect and alarm ground fault of PV system or battery system and also operate with System Monitoring Unit for real-time and remote monitoring the system data and parameters on local computer or website.
