W@P's Solar System

So yesterday the inverter tripped with an F34 AC Overload error again. But it restarted immediately. I had one AC running, a vacuum cleaner, and then the 2 geysers kicked in ass well. And suddenly the power went out. It was exactly at 13:00 and the power was supposed to come back at 13:00 as well after LS.

Must just be an unlucky combination of events that took place right at the same time.

Glad to hear it was ok, yeah the overload switches system off when not connected to the grid and then comes back after a min or two once you have reduced the load. Happened once or twice to me to.

Oven, kettle, dishwasher two induction plates :P

Haha we also had an issue last night that required a specific sequence of events.

Battery bank is 9.6 kWh at 0.5C so can supply a max load of 4.8 kW.

Had the heater on, wife went to put the kettle on and everything went off. Inverter had F56 error and batteries shut down due to overload.

Turns out the prepaid ran out and there was nothing to supplement the additional load...

Luckily you didn't have to go next door, "ciu in hand" to play the game of trying to reload tokens
 
So with the temps falling and winter on its way I came to the conclusion that my water is not hot enough anymore by only running the geysers on the timers from 13:00 - 16:00. The warm water in the mornings is not hot enough even on full warm on the mixer. So I put another schedule on one of the Astutes for only one geyser to start up at 06:00 for 30 minutes. Works a treat. Water is way hotter than needed. I think I can even change it to 20 or 15 minutes.
 
I eventually convinced my father to get a backup system.
8kw Sunsynk and 2 x Hubble Am-2 5.5kw batteries and everything else that is needed.
Panels will come at a later stage.

This was the quote from Steve at Powerforum Store.

This brings the total amount spent at Steve to R264k between me and my dad's systems. Fscking eskom.

Is there a specific reason to spend that on backup only? Can you not install some panels instead of an extra battery to start saving right away? Would help to offset the money spent on getting the system.

Or even a 5kw Inverter?

Excellent price :cool:

When the AC failed, the inverter went onto battery. All good.
I decided to charge the battery with the gen and used the changeover switch.
The inverter showed AC but would not take any power.

I then upped the maximum HZ a little and the Sunsynk was happy but only for a few minutes. Then it would try to connect to the gen again, just to disconnect a minute or so later.

I then connected the gen directly to the AUX port.
The inverter was happy and charged the battery for about 40 minutes and then disconnected and refused to accept the gen again.

@Steijn1 May I ask if you found a solution to this issue? I'm having the exact problem. My inverter is connected on the home side of the generator auto changeover switch. As with you, the AC light comes on when the generator kicks in, but the inverter shows no current from the grid.
Thank you.

We still have to assess the roof space before deciding on the panels. He just wants a backup solution in the meantime. Also, he has some peaks during the day between 5 kW and 8 kW so we decide to take the 8kw inverter.
Also don't want to split anything on the DB so everything will go on the essential side.

This was the deciding factor for us going 8kw, we continue as if nothing has changed 5kw means you have to think twice typically before switching something on.

Hi,
I have to confess I have not tried again.
What I want to try is reduce the charge amps.
Hoping that will fix it.

I got mine to work.
I have a three-phase generator, and obviously, only one of the phases powers the inverter. If the total load of the generator is low, the frequency creeps above the maximum set on the inverter. When there is a load on the generator, the frequency stays within the inverter's parameters. The times I checked the frequency on the genset, it had some load which made the frequency settings on the inverter appear to be fine.
If the frequency goes too high during the time before the inverter starts to draw power, it fails to kick in. (My guess is that whenever the frequency goes above the set parameters, the countdown on the inverter starts again.)
Setting the maximum frequency well above the normal operating frequency of the generator when carrying a load resolved the issue.

If the frequency is within spec, check that the generator has neutral and earth bonded. (measure the voltage to earth with respect to neutral from the inverter. It should be 0V)

Will definitely check.

If you buy it from Powerforum who installed it though?
