Hi. So we managed to stop the system tripping and it switches over perfectly when there's load shedding or main power is lost, we ran it today and no issues . The problem we have now is that we had load shedding at 8pm, every switched over perfectly and system ran but after 35mins the system switched off, nothing tripped but the inverter turned off/shut down. Reset it and it shows batteries are almost full but again switched off after a while. I know obviously the panels are not charging batteries because it's night but (bearing in mind it shows there is battery power stored) why in day there's no shutdown but at night when load shedding there is?

What is strange is that the installation was completed yesat around 14:30pm. It was running perfectly. At 6pm load shedding kicked in, the ATS (BOTH) kicked in and the system ran perfect during load shedding till 8pm and when Powe came back on again both ATS switched over. No issues over this period till +-1am when app for alarm system showed a drop in AC power and that's when noticed that solar system shut down and no power to pool house or laundry /garage. This morning switched system back on and repeatedly kept tripping and every time at different time intervals. Stayed on between 5mins - 1hr but kept tripping. Eventually bypass system and put everything to run from mains till we figure out the issue.

The system is situated at the 2nd sub DB +-50m away from the main DB. The cable running between DB's is only a 2 core so we cannot have main power running to the sub DB's and solar power running back to the main DB on 1 cable. Where the system is situated we need main power and not only solar as we use welding machines. So the solar system needs to feed back to the main DB in the existing cable. Thought was that 2 x change over switches would be needed. When load shedding kicks in the ATS at Main DB switches over and so does one at system and then power feeds back to main DB to feed house. We not sure what is tripping system, haven't figured out yet. There is a plug circuit breaker which is tripping the mains but when solar system on it doesn't trip imme, only after a while. My brain is fried on this one, so many scenarios 🤔

Can you please help. I am having big issues with my system. System installed is attached (6 x 455w JA Panels). We have a main DB with 2 x Sub DB's quite far from the house and main DB. Instead of running new cable to the main DB we installed 2 x automatic Change over switches. One at main DB and one at the System and sub DB. For some reason last night when there was load shedding the change over switches worked 100% and solar system kicked in and ran during load shedding with no issues at 1am the system tripped/switched off. Reset in the morning and solar system keeps tripping, each time the intervals between trips is different. It can't be that the batteries power is depleted as it is during the day and there is sunshine and inverter was showing batteries were charging. I'm not sure if change over switches are not communicating properly. Not sure if it's because of settings. Have now re wired the change of switche at main DB and set sub DB change over to manual so that main house, poll pump house and laundry and garage are running only on mains. Idea is to have solar system only feeding back to main house during load shedding. Pool house laundry and garage to run off mains and not solar. Big challenge 🙈🙈🙈💩💩💩

Can anyone assist with the settings? Have 6 x 455w panels, 2 x US2000 Pylontech lithium batteries. The system only gets charged by the panels and not by the mains at all. Then feeds the property with power during load shedding.

Managed to switch it on by holding down the 2 red buttons marked "sw" together for 3+ seconds.

Thank you so much for the reply. Much appreciated. Can I take the batteries and get them charged somewhere? I don't want to just stick a charger on myself and damage the batteries. Thanks again.

Hi all. Please can you assist. A backup system consisting of a Mecer SOL-IX-AX-5P inverter and 2x US2000 Pylontech lithium batteries was removed to be relocated to another house. Batteries stood +- 3-4 weeks before the system was re installed with 6 x JA 455w panels. The invert will now not switch on. The batteries voltage is 0.068V. Does this particular Mecer inverter only switch on with battery power and not mains? Thank you

Hello. Can someone please assist. A Mecer SOL-IX-AX-5P inverter. Can it only switch on with battery power and not mains? Inverter was connected to 2 x US2000 Pylontech lithium batteries, then System removed to be relocated to another house. Batteries have how discharged and the inverter will not switch on. Thank you
