Eksteen

Thank you guys. That does make a lot of sense. It does have an internal battery running on about 10V. It shows that on the display. That should be enough to show an error code I would think but obviously it does not. Seems like I will have to beg buy borrow or steal a battery. I will give feedback as to the outcome. We will have to wait and see when the next thunderstorm comes around.

Thanks, I appreciate the input. I am not electical enough to have thought of that. Easy enough to try. I will have to wait for the next lightning storm though.

Sunsynk 5kw super hybrid. Ight under the second panel. DC fused and surge protected, + and - seperately and two strings each seperately. All panels grounded to each other and then to metal trunking and then to earth peg. Surge protection connected to same earth. At the invertor the house DB earth is also connected downstream of the invertor to that earth. (Three connecting points, live neutrel and earth.) Aluminium body also connected to the same earth. Currently no battery yet and no essential load. The whole house runs off the input side to the invertor like non essentiel loads.

Nothing on the logs and no fault codes. The last 2 nights no lightning and no problem.

I would tend to agree with that logic. I have surge protection on the PV but not on the AC. (In 40 years never lost anything through the AC) PC cables are running in metal trunking from right next to the panel to where it goes through the wall. It is also connected to the same earth as the panel frames and surge protectors.

I am brand new here. I have just done this installation myself. No batteries yet. It seems to be an over achiever so far and I am highly impressed. Question: The last 3 nights we had serious lightning storms in our area. It seems that the system switches off and does not come back on. In the morning everything seems fine, but in the top left hand corner it says OFF. No power is generated even though the sun is shining. I then do a shutdown procedure and a startup procedure as per the manual. The system then comes back ON and performs normally. There are no fault codes registerred for these events. Is this normal ? What have I done wrong ? Could it be an installation fault or a setting fault ? I cannot think that it was designed this way. Any comment or possible solution would be appreciated. All the panel frames are linked and properly earthed.

Hi, I am a newbee here. Please tell me if I transgress somewhere, it will be a matter of stupidity. I started up my system 3 days ago. I did the installation etc myself. (Probability of getting it wrong is definately there.) Seems to work as intended, Sunsynk 5kW 1 Phase 8 x 400 W panels in one string on one MPPT for now. No batteries for now. (No batteries ticked in setup.) Very simple connection currently. Supply from Escom, then CT, arrow with flow, tee off to the earth leakage supplying the whole lot, then carry on to supply the invertor. Full stop. No loads on the other side. Ct wires into connection block on ports 2 (White wire +) & 3 (Black wire -) as per manual. Day before yesterday it produced 16 kW Metering does not quite add up. Suspect something with CT and need some pointers please !!!! It is dark already, so no power from the panels. I measure 7 A with a hand clamp meter right next to the inverter ct. The display on the inverter alternates between 0 and 0.6 A. How do I fix this ?? I have tried to turn the ct arround, no difference, then swopped the ct wires around, no difference. then uncoiled the ct wire ball, no difference. Any suggestions please ??? Pieter
