Solis 50kW Solar Inverter - Three Phase - 4 MPPT with DC Switch (Example Image)



This three phase output inverter’s slim and lightweight design allows a two person install with ease. The inverter is aesthetically pleasing and is suitable for commercial environments. It has over 98% max. efficiency. The inverter is IP65 protected alongside several other protection functions. The input voltage range is widespread as well as having quad MPPT design with precise MMPT algorithm. WiFi and GPRS are optional interfaces which can be purchased separately and retrofitted at any time. A WiFi and monitoring app is available to allow the user to monitor their system remotely. This inverter comes with a 5 year warranty as standard but can be easily upgraded to 10 or 20 years at a low cost.
