So firstly I live in western cape and have power supplied by city of Cape Town and I have a prepaid meter installed. Middle of last year I had a system installed by someone I was assured by a family member to be legit and now almost a year later I started finding out he maybe wasn’t so legit and that there’s problems with the installation which would prevent it getting certified, after I had to call out someone else about certification because the guy who installed the first system never came up with the certificate he promised. So it was suggested by the new person that I replace some, actually most of the stuff, so I just want to see if I can get some advice or suggestions because I don’t want to get burned again. I am 70+ years old so it was impossible for me to get onto my roof to see what the first guy had done, but I’ve been told by the new company I contacted about certification that there’s a lot wrong like wires from the panels just laying on the roof, plugs deteriorating after less than a year, not enough fuses and multiple panels being joined together into single fuses etc. I will tell you what I know about the system and problems I encountered and also upload some photos of the stuff I can get to and also the system the new company suggested. So the system I have is a Sunmagic 5kW 48v hybrid inverter, N Energy 100ah battery, 6x 460w Canadian panels and 2x 560w Canadian panels. The wires says 1x 4mm2 running from the panels and thicker wires between battery and inverter. The panels I was told is connected up in 2 parallel groups of 4 panels in each. I had a problem where the circuit breakers from the panels would trip if I don’t switch off I group of panels between 10:00 in the morning and 16:00 in the afternoon. There’s a double pole circuit breaker on both the positive and negative wires from the panels, and it’s always the breaker on the positive side which trips. I heard someone discussing that there shouldn’t be breakers on both the pos and neg lines but haven’t had anyone tell me if it’s right or wrong. I also have a 19kw Alliance pool heat pump which says it’s running current is 0.29 ~ 4.03kw which is not installed yet so the new company suggested I get either a 8kW inverter or I use my current sunmagic 5kW alone for the heat pump if I have a new 8kW inverter installed. The new installation suggested by the company is Solarsynk 8kW inverter, Hubble 5kW am2 battery and additional 10x 460w Canadian panels and new breakers wires and all other small parts required for the new system installation. i asked if I could use the current N energy 5kW battery with the new Hubble 5kW battery they want to install but they said no because the Hubble is 51v and N energy is 48v. Some things I read about in your forums was I noticed you do get the Hubble in 48v as well, would that make it possible to add the 2 batteries together and if still not, would replacing the N energy battery be necessary considering it’s only about 6 months old. Also I read about Hubble am5 batteries and that they apparently better than the am2.
