Does anyone have advice on if the SolarEdge quote is worth it over the extra battery storage, EPS and lower cost of the GivEnergy option?

The GivEnergy quote uses an all in one battery system with EnPhase iQ8 Microinverters for each panel.

I would think ability to run off grid in a power cut is a big advantage. I take it the GivEnergy batteries need their inverter rather than running via AC coupling?

The only thing about combined solar/battery in the DC side is that monitoring by other systems of the sit between the two isn’t possible with CT clamps, so things like car chargers/solar diverters can’t tell if a battery is draining.

Quote says “GivEnergy All in One AC Coupled System with Gateway”.

One thing I’m waiting on is confirmation that both systems will be ‘smart’ with our Zappi Charger and ASHP system.

You can have the circuit designed so a inverter doesn’t see the car charger, or control them via Home Assistant to not discharge when car is charging.

Of course, I forgot that not everyone has Space Karen in complete control of their house batteries.

I’ve often been an advocate of tidal power, but this thread highlights many of the challenges:

It still seems like a great idea, as it’s predictable and contains a lot of energy, but seeing some of the challenges is eye opening. Cool stuff.

Oh yeah.

Had to fight with Octopus to stop it draining the battery though.

Remind me what tariff you’re on. Why aren’t you just exporting it?

1156

Old style FIT so deemed 50% export.

And the whole Good Life self sufficiency thing.

There is a comments section, which is exactly how you would expect it to be.

Quite sunny today, from the start - battery was full early :+1:

My energy news - Since Solar install in September we have just completed the first 7 day run of net zero cost. 31Kw of exported energy offset the standing charge and less than 1kwH in total was taken from the grid for the prior 7 days. About ÂŁ20 clawed back.

Annoyingly the whilst the overall energy price recently dropped from 30p to 24p per unit the standing standing charge increased by 15p a day - buggers.

Curent national stats. I would suspect the gas generation is running at its minimum to keep it up to temperature.

Going well today so far :+1:

Is the self sufficiency % figure a cumulative use figure Jim?

Looks like for today you have produced 300% more than your use for the day.

1166

Yes Chris, I think that % figure is deceptive. It doesn’t include the excess pumped into the grid.

Am envious with my 22.8kWh today. You so need an EV.
