Just my tuppence worth, nearly 4 years ago I invested in a system comprised of a Kodak 7.5 inverter ā not the cheapest either ā 14 panels and two Freedom Won 5/4 batteries..a year ago approximately I went to visit family in CT and on my return found the Kodak had died on me with the obvious results of everything in freezer being not toast..š getting the agents to honor the warranty was so frustrating that I gave up and opted to have a Sunsynk 8kw installed ..not cheap but has a lot more going for it..if it goes down Eskom will automatically be switched in to save the day so to speak..however Iām not a very trusting person so I have a gadget called SimPal which has a SIM card it gets plugged in to any plug in the house and will send a sms ā power lost ā or ā power restored ā whichever the case is and then I can call in the troops who have access to my home to sort it out.
