UPS ?

Have you considered V2H in the future in your set-up?

Uninterruptible Power Supply - so if the grid supply fails the house battery takes over almost seamlessly. Even if there is a bit of a flicker the core IT already has local higher grade online UPS systems as I rely on them for work.

The difference is that the existing IT UPS run off small lead acid SLA and have a runtime of about 20 mins, they give the NAS enough time to shut down safely and keep the internet active during short glitches, which tends to be mostly what happens during storms. The house battery potentially has run times of several hours depending on how much I want to reserve for that.

I would have liked to tinker with V2H or V2G as currently both our vehicles sit on the drive much of the time. However the i3 is ahead of its time in many ways but only did V2H/G as part of some specialised business trials.

I'm still not used to watching the house draw about 10kw at night as the house battery, overnight washing and EV charging kick in on the heavy days...

Yeah, it's a real shame BMW didn't evolve the I3's and others with V2* technology.

I've got a feeling it's going to be a big thing in a decade as storage is not keeping up with generation.

Just a very small solar project I made up a few years ago with a spare leisure battery from our caravaning days and a flexible solar panel bought for some other idea that went in a different direction. Got a battery box that was a bit longer than the lb which gives room for the wiring, 12 v socket and connectors. The plastic box for the dual charge controller is a bit naff but it was during lockdown and just what I had to hand. I use the battery as a 12 volt supply when using tyre inflator or other 12 v kit and saves risking blowing a fuse in the van using one of its 12 v sockets. The charge controller allows the panel to charge the lb and another battery connected with the croc clips.

Have you ever managed to quantify how much difference it makes in the data?

Just curious as my roof array is now 13 years old and in the annual data doesn't really show any drop in generation due to wear or dirt. If it was easy to clean I would but it's around £100 of kit (or local window washer) and I'm not sure it's really worth that.

First two days of 100% solar powered household.

Finally turned off the over night Grid charge to the battery bank.

Slowly decreasing from 4hrs to 30mins.

And now off.

Now using the solar to charge battery and run the house, the battery bank has enough capacity to run the place for 24hrs.... Average 25kwh. Per day.

The solar shed is also doing well.

We are now generating more power than the garden lights are using...... So that's now self sufficient.

We're using 3* 100ah 12v lithiums as storage batteries.

But needed to use the NOCO or Victron 12v chargers to keep the bank topped up over the dark winter months.

Now the sun is back out we are doing good.

The solar is 4* 100w rigid frame panels hanging vertical on the side fence.
