Be careful of the inverter installer

Not great. Arun, the man that installed the inverter, did not understand the system he bought me.  After he installed the inverter he letters and it kept tripping every 45 mins to an hour. He can back the next day and it was because he set up the batteries incorrectly. then 6 weeks later the system turns off never to turn on again and he has not come back to fix anything. 2 weeks of not coming to fix the issues and we sit with the R55000 system that is not keeping the lights on.
