Hi, sent you a DM.

My installer did a great job on sizing this system. Looked at our peak power usage as well as average for the day. The highest peak I have seen was 12KW load, and what you need to remember is that even if it goes over 15KW it will then share the load between the panels and the batteries or grid through the inverter. Let's say it's 5pm and the solar generation sits at 4KW. If the yard is using 7KW at that time the other 3KW will then be supplied by the batteries or grid if batteries are empty. The system can handle 24KW total which will never happen. Regarding the amount of panels. If our batteries are at 35-40% at 7am in the morning, which is where it usually sits on average, the panels are able to charge them to 100% at around 12:00. So currently I don't see the need to add more panels except if City of Cape Town starts giving me loads of cash for pushing power back into the grid

Thanks gents. Yes that is a projection from the simulation done by the installers. It also takes into account sources of system loss in the graph on the right.

Hi all. Want to share my Sunsynk solar system recently installed in June. Specs: Sunsynk 12kw hybrid inverter x2 (24kw) 3 phase 14.3kwh SolarMD lithium batteries x3 (42.9kwh) 380w JA Solar black frame panels x40 (15.2kw PV) John Deere 40Kva generator linked to inverters as a last resort backup.
