I think most of us here got use to solar and hardly ever experience a power outage.
When I was staying in Phalaborwa, my battery bank was sufficient to get me through the night, I moved that system as it was to Pretoria and am sitting with a oversize PV array in an area that is not suppose to see loadshedding. In addition to that the children is growing up fast and interests changes constantly.
My 14 year old daughter started her own business. She is breeding fish and growing aquatic plants. All of a sudden there is over 30 aquariums on the premises, all with a heater of between 50W and 300W. Constant load of about 2.5kwh just for her. With 4 geysers, swimming pool heat pump and the normal loads we exceed 6kwh often and peak at about 9kw.
My house is fed from an overhead line across the road. The 80A breaker feeding my home is right on top of that pole, not covered and exposed to the sun and rain for over 2 years from what the previous owner tells me. From the time we moved in in September, this breaker will randomly trip. Lately at 04H20 (20 min after one geyser started) and roughly 12 noon.
First it tripped when VRM recorded just over 40A, but as time went by, it tripped more frequently and is now tripping at as low as 22A at noon when the breaker is nice and hot from staring at the sun the whole day.
I allow self consumption of the battery and because of the banks small size and the high loads, the battery cant handle the load from the early morning trip till the MPPT’s kick in and normally just before we wake up in the morning, the battery runs out and everything is off. The sun hits the panels just about the time the kids are at school, so every morning its chaos getting them ready for school in the dark. Quite stressful after not experiencing a power outage for years.
I have been reporting this issue for months, but as we know, nothing gets done. Even got the number of the electrical supervisor and explained everything to him. Got told to get an electrical contractor with recorders to prove its not something in my house tripping the power. So i started sending him VRM reports and that confused the situation even further. We are currently experiencing 2 trips per day and this afternoon at 4 I decided to complain on our local ratepayers group. I knew there were a few counselors on there that is still shopping for votes and send them them a video of the breaker that was not covered and explained the situation. Just before 6, two very upset council electricians stopped at my house and went up to reset the breaker like they did 100 times before, everytime promising me they will return with a new breaker and a cover to protect the breaker against the elements. As the guy got into his truck to leave, I asked him when I can expect the new breaker. He said I must rather fix the problem in my house. After some serious conversation, he took the breaker and cover that he was send with from the seat next to him and completed the work.
Kudos to the councilors for getting right (in less than 2 Hours) what I could not achieve in a few months.
Note:
For those who read this and thought, “Okay the trip at 4 am makes sense, but why does Jaco exceed 6kwh at noon if he says he’s got too many panels”
Well sometimes my old SD meter does an about-face and the system donates more than 6kwh to the guys who keeps on resetting my breaker.
