Ahhhh, but that can be fixed with a larger Sunny Island and more batteries.  stir

I feel somewhat deprived.
                      All you guys and your codes get to test your IQs on a regular basis. You can even phone a friend in Switzerland and yodel down the phone about the terrors of errors. I'm stuck with the smiling Chinaman who forgives everything and will never fail to restart when overloaded. No exciting loud bangs.. just this decade long + reliability. Oooo.

I know what you mean Biff. I just sold 3 smiling chinamen on ebay, I did shed a little tear but I know they went to good homes.
Completely rusty but still smiling.

 Aye Roger,
             That,s him. Great chap and ultra reliable. I have the twin of that looking after a large bank in the shed, just for lights and small tools but mainly for keeping 20 batteries topped up with solar.
  The house controllers are all 2kw x 120v  with 1 separate 2kw inverter.. However that 48volt model in your pic is one of the most reliable and simple to operate that I have ever put my hands on.

Good Morning All,

Problem with expansion is that it is clear that there is more than one of us on this forum alone who are looking to pick up 'cheap' second hand Growatt batteries.........

I took the decision yesterday to not charge the batteries overnight and leave the SHM 2.0 to 'do its thing'. The Zoe was also put on charge again, 3rd night running. The battery was down to 15% this morning and currently the PV generation is creeping up but not yet met the house demand. It is due to be a sunny day so the battery charging will take place at some point, according to the manuals the bulk of the charging should take place after midday to reduce export limitation cutting in.

I'm now looking at how to let the 'system' better know what is going on in terms of power usage.

It appears that the system is making better projections of actual PV being produced but is still being defeated by not 'understanding' the loads. I'm also 'confusing' it by operating such as the washing machine and tumble drier yesterday afternoon - https://www.sma-sunny.com/en/intelligent-storing/

I've just ordered an Edimax SP-2101 radio plug thing to try out.

Regards

Richard

Good Evening All,

The system tripped a couple of times today. Investigation has shown it to be operator error.  When inserting the rigid, fingered copper, live busbar in to the RCD and four MCB's it has obviously gone the wrong side of the terminal clamp on the 32A MCB to the inverters and wasn't making good contact.

Problem now sorted so hopefully we'll get a full run at battery charging tomorrow. Zoe not being charged overnight.

Regards

Richard

Hey Richard,
just something I was thinking about.  I believe LION batteries really don't like being charged in sub zero temperatures.  I can't remember if you said if you were boxing them in, but it would be worth having them boxed with some heating wire in the compartment if they are staying in the shed.  I was wondering how they got away with it on my leaf and it turns out there is a battery heater.
Cheers
Andy

Shame this thread died, I was enjoying it. It doesn't seem to have reached a natural conclusion.
