Hi Madness za That's how I also know it but now to find the same inverters is causing me headache.

Good day everyone. I currently have 2 x 8kVA Five Star inverters connected in parallel. I want to add a 3rd but struggle to find the same inverter model. Will I be able to add another Five Star 8kva inverter in parallel with the current 2 if the models differ? See pics.

Good morning, Everyone I will be connecting 3 x 8000kVA Single Phase Inverters in parallel. The system is totally off grid. What would be the best way to combine the 3 ac outputs into 1 supply to the main DB EL? I bought 16mm2 cable, so wiring size shouldn't be a problem.

Hi frivan Thanks for the info. I will be using a 63A EL. House is already off grid so no supply from utility to inverters. I was also looking at 16mm2 cable, but they are costly. Maybe someone know where in SA I can buy a 20m cable.

Good evening, Everyone I'm planning to connect a 3rd Fivestar 8kVA inverter in parallel. I need to know my wire size from the 3 inverters to my EL in my Main DB. Can I run a 6mm2 cable for each inverter from there AC Breakers to the Main EL or does it need to be only 1 cable of a certain size? Need some clarity please

Hi Everyone Thanks for all the good advise. It's been 4 days after I installed the new combiner box. Have been checking the temp with my thermal gun as wel. All wires and breakers ice cold and I've been running my whole house off the solar except for the gas stove. I will wait a few more days and then re tighten everything again.

Good evening I have double checked the new box for loose connections. Old box was definitely DC breakers, same with new one. 40A each. Unfortunately, no photos of old one. Current was about 12.5A from each string and 325V.

Hello everyone. 20 March was a bad day for me as we almost had a fire started in the house. I installed my solar setup about 3months ago. It worked fine until yesterday my wife started smelling plastic burning. She rushed to the inverters and found smoke coming from the PV Combiner Box. Immediately she switched off everything until I got home from work. After investigating, I found the Surge Protectors, plastic covers melted. I rushed to town and bought a new Solar Wise Metal Case PV Combiner Box. Much steadier and really of decent quality. I just can't imagine what would have happen if nobody was home. Any suggestions why this could have happened? First pic is the melted plastic box and the other 2 the new box.

Hi They are 2 x Fivestar 8kVA Inverters

Seems to me that's exactly what's happening now.

Hi Everyone I moved my Aqua Max 600W pool pump onto my inverter power. Now it runs for about 15mins then shuts off. Motor very hot. First, I thought it was the pump, so i got a new one. Same problem. I have 2 x 6kW Inverters in parallel with 6 x 5.12kW batteries and 16 x 550W panels. It should be more than enough power to run a 600W pump. It only started after I connected it to solar power. Any advise

I almost forgot to ask. What is the standard if you want to route your solar panel wiring through the roof and then out underneath tiles down outside wall to earth rod?

Hi everyone I'm currently in the process of going off grid. I have a few concerns about the earthing and the earth/neutral bond. My panels are earthed directly to a copper earth rod in the ground. 1) Can I still use Eskom's earthing rod going into my DB as this earth is still the best you will get? If not, what must I do? Currently all my ac earths are connected to earth rod in main DB. 2)Can I feed a 6mm wire from main DB earth rod to my inverter? 3) Where and how will I do my permanent earth/neutral bond once the prepaid meter is removed and fuses pulled from mini sub? Oh! Please try and explain in away that a stupid diy guy lime myself can understand.

If I understand correctly, I'll be fine with 250A busbars. Awesome. Thanks guys, much appreciated.
