Plug in solar

TroubledTarts

And ecoflow for an ad banner for suggesting you can sit plug in solar before the regulations are approved.

It will feed 150wh into the house constantly to remove our base load.

Sounds like a good idea.

150 watts continuously is 3.6 kWh/day, so I think that'll take care of most of your generation as things currently stand?

My sunlight stops when it gets dark !

My sunlight stops when it gets dark!

I suspect that @TroubledTarts sunlight also stops then.

I also suspect you missed that they have an Ecoflow Delta Max battery connected to their system. That has a 2kWh battery that will let them continue their 150W discharge through the night, at least during the summer months.

Yea sadly I have not managed a way to make the house levitate and move with the sun 24/7…but one day we know hoverboards for houses will be a real thing !!

Sunny days like today I can take my base load of 150W out and the solar still leaves me with a full battery when the sun stops shining(sometimes even a little syphoned off to another battery I have)

What I also do is supplement the dull days charging my delta max up in the cheapest agile slots for that day and discharge when the prices are high. I expect this will become more of the norm in winter to cover the base load.

As we are drawing a little more right now I've set it to 200W and the reason I use the delta max is that it has a 100V solar input so I can run two panels in series. The delta max 2's have two ports of 60V each which I intend to abuse at a later date.

Still on the hunt for two more cheap panels nearby as the prices at city plumbing have sky rocketed.

Lidl Germany is selling a ~2kWh battery with built-in solar inverter (so a bit like an Ecoflow Stream Max) for €299 / €399 (cheaper price with Lidl Plus) and a 10-year warranty:

Site in German, automatic translation works fairly well in Firefox so I suspect Chrome/Google etc. should handle it too.

Edit: see below, this unit might not include the microinverter. So that's an extra €100 or so.

I have had a look at this, but I cannot see any positive ROI over the expected life of the product, even with ideal generation and perfect usage patterns.

Great price and that 10 year warranty means it pays for itself within the warranty period.

Can you show your maths, as I'm confused by that statement?

Obviously, I wouldn't expect ideal generation and usage, but if so as you state, then perhaps 1,000kWh pa from 1kWp of PV. At 25p/kWh saving, that would be ~£250pa.

Let's go with ~£350 (€399), plus £150 for the panels, then that's a two year payback. At less than ideal generation, and harder to displace all gen against import, then 4yrs(?)

Am I missing something?
