Solar PV battery options

Does 'plug-and-play' mean what I would hope it does for this; you wheel the pack next to your hybrid inverter (Sofar in my case), connect whatever cables are needed between the two (I would guess one for the power itself and one for communications?) and then it is all set up, the inverter and the battery communicate without any more set up needed and the battery appears within my Solarman Smart app?

Or is it a tab more complicated than that? I just don't have the time or patience for any installation or DIY work, so either want a totally painfree solution or failing that, paying someone to do it for me!

Deligreen says their batteries are compatible with Solis, Sofar etc. If the CAN supports it, then it should do with some minor settings. Depends on the Inverter model in how to access and set the correct settings. I asked ChatGBT this and it gave me a pdf answer that may help.

As I am new to this as well, there would be others on this forum that would be best able to guide you. Also A.I would give you most of those details.

In my opinion, just put the inverter to use Voltage

The BMS will still manage the battery but most people will confirm that SOC from them can be just as crap as from the inverter.

You are better to discharge to xx volts rather than xx % as the % can drift

Deligreen received a delivery of batteries at the their warehouse in Poland on 1st April so deliveries to customers shouldn't be all that long.

if I want to charge my battery faster understand I can use a rectifier, does anyone have a recommendation? Do I just attach it to the battery terminals and add some sort of timer that matches my charge settings.

@Fantana2 That's basically it.

To a point, you need to pick a voltage. I would suggest 56v or 57v

I got whatsapps from them. Their current stock is sold out and the battery will arrive in Rotterdam in 4 weeks. So I assume 6 weeks aswell. First world problems.

I got my solar installed Monday and a quick question. I asked Google Gemini but wanted to confirm, is it best to always charge batteries at night rate and export as much as possible during the day? Initially I had the Solis set to not charge from the grid at all, only get solar but someone said I'm better always exporting to the grid if possible since the night rate is 12.5c and feed in is 18.5.

So is that correct, would it be the same for my eletric car also? Always still charge it on the cheap night rate and let as much solar be exported as possible?

Just to mention its a 5.2kwh array and the battery is 10kwh dyness.

So would it still be the optimal setup?

Thanks for that. Yeah so I was coming to the logical conclusion that the battery should not be charged from solar, and only charge at the night rate?

Actually looking at it again you have a Solis Hybrid inverter I presume, so that works by taking your DC solar PV and sending it directly to the DC battery so that is very efficent so I wouldnt worry too much. But still everytime you are converting from AC to Dc or in and out of the battery its going introduce losses.

My system is retrofit where I have just a simple Solis PV inveter so to get my PV into my battery I have to go through another Inveter charger.

The overall max permitted under NC6 is specifically 25A - so approx 5.75kW.

So you could get a second hand 3.6 hybrid

What size is your biggest house draw. For the few times going over 3.6kW and using the grid, surely not a lot

PM me, have a second hand 3.6kw Hybrid that I will be putting up on Adverts.
