Naks' Solar System:

Oh was that cumulative? Sorry i read it as point in time

No, that was peak for the day.

I must still create the cumulative charts

 

[Naks]

OK, cumulative figures:

How is your system going @Naks? What was the cause of the issues with the MPPT's?

 

[ADrunkTeddyBear]

The interface and software on the Victron is nicer... But also its modular which means if one mppt is down, you replace it. Sunsynk is an integrated unit. If you lose an MPPT, the whole unit needs to be replaced or repaired. Still, it's a chunk of change to pay for the modular approach.

Yeah the modularity of the victron is handy. Especially since you dont have to RMA the whole unit if something breaks

At R16k per MPPT controller I hope they don't ask question if it breaks and just give you a new one.

Going like the clappers!

It wasn't the MPPT, we figured out that when we did a test reset on the system, we mistakenly switched the inverter to 'Charger' mode only via the 3-way switch.

Once they informed me, I switched it to 'Inverter' mode and everything was fine, zero issues since then.

Since the installation, roughly 87% of our consumption is solar:

Great to see

So, this annoying Earth Leakage trip is still happening everytime Eskom comes back online: https://mybroadband.co.za/forum/threads/the-battery-thread-solar-inverter.1071211/post-29002168

First we thought it might be the wine cooler, which is very old and running quite hot, but I left it unplugged before the previous loadshedding and the EL still tripped.

I've now left our main fridge unplugged, let's see if it is the cause.

Any other suggestions?

 

[Naks]

ffs...

Now it's also tripping when loadshedding starts.

And it's not the main fridge, the Earth still tripped at around 4am when loadshedding started.

I unplugged the kitchen extractor unit, EL still tripped when Eskom came back on

Sorry to hear about your issue. I had an issue where my EL would also trip randomly, that was before I had the solar system. Had the EL replaced and all was good after that.

I have a few plugs where the electrician's testing machine shows there is no earth. I am not using them atm. Maybe it could be your issue? That there is broken earth on one of your plugs or light switches. Don't know.

Any lights outside potentially getting more rain than usual?

 

[Naks]

You on prepaid?

Nope.

Nope, no rains really to speak off recently.

 

[Snyper564]

Maybe not the ultimate solution but if you have enough pv and battery power switch off eskom during this loadshedding time

Yeah, I'm going to have to, since we're away for the long weekend.

 

[Mike Hoxbig]

Switch everything off before the power comes back, then bring them up one by one until it trips?

Had the same issue, after several call outs eventually changed the EL and been good since

Yep, can try that. That's me up at 6am again tomorrow then

but I don't think it will trip if I do that, since nothing happens when I manually switch the grid off & on
