Solar PV battery options

Still perfect nothing wrong not one issue with it i have done 110 cycles of it so far.

The Docan Panda (32kWh) battery has sold out. Won't be back in Europe for another 3-5 months. I might take a chance with Deligreen.

Great post – lots of useful info here.

I’m planning to set up a battery storage + inverter system, but without solar panels for now as I’ve roof work planned later in the year.
The idea is to charge the batteries on the EV night rate and discharge during the daytime.

My daily usage ranges from ~10–30 kWh, depending on the season, so I’m currently thinking having of two 15 kWh batteries.

A few questions for those who’ve already done this:

• Is stackable battery storage generally the better option?
• Are Deligreen and GobelPower still the recommended brands here?
• Any specific battery + inverter combinations you’d recommend for a battery‑only setup (with solar to be added later)?

Open to all advice, especially from anyone running a similar setup. Cheers!

its definitely a orange flag, but it doesn't necessarily mean there is a problem with the battery or it's quality.

I had a similar situation with Mammotion robot lawn mowers years ago. They reached out to me to do a video for their kick starter and they had the same reaction when I made similar requests.

The outcome of the Kickstarter was there was delays with the mower, but people did get their mowers eventually and by all accounts they are considered very good mowers. I've since bought one myself (a smaller model)

If the battery actually costs them €1000 or whatever, they potentially see value in paying you €1000 to do an ad for them, they don't see value in paying you €1000 to review the battery.

If a person is handy enough with DIY and bought, say, the prebuilt below—one that has EVE cells and a JK v4 BMS—you’d assume any issue would likely be a dodgy cell or BMS. These are items that can be sourced separately and swapped out.

It’s a pain in the arse, but it's doable; especially considering these batteries are about 1k less (including delivery and in stock) than the next comparable options from Fogstar or NKON.

The Deligreen DIY kit ordered in mid-March took a month to deliver, arrived a few days ago.

Spent time today setting it up and made good progress setting up the cells in the battery box directly in the attic.

However, assembling the BMS and front panel is proving to be a different challenge.

I’ve made some progress (I think!) but not entirely sure where the heavy red and black cables all need to connect from the battery terminals to the BMS, and from the BMS to the front panel connectors, through the fuse.

I’m kinda stuck at this point:

Has anyone come across any good, detailed assembly videos or instructions for this battery and BMS?

How have ye guys crimped the 25mm sq DC battery cables for the DC MCB?

One of these?

If anyone is in Dublin and would just prefer pre-built, then this is possibly a decent option

Deligreen 32kw delivered and in place, heavy but the 6 wheels back it easy to move. I (stupidly) assumed it would communicate directly (like the existing pylontechs), any guide on what settings to input in the solis and jkbms app?

Would you mind posting a larger picture of those two settings?

Thanks @al2025

Thanks a million.

Anyone?
