Server battery rack recharging

[MegaBlindy]

Hello, I'm looking to expand delta 2 max, but what ecoflow are offering is not enough for me.
At the moment i have a couple solar panels connected to the ecoflow powerstream, which supplies my home with enough juice for what I need, but 2kwh is just not enough for the winter months.
I was looking at power rack to connect it to xt60 connectors on the delta unit. My issue I have no idea how to recharge it without a professionally installed inverter to the grid.
I'd appreciate the help

Just use a battery charger ?
So you can charge it by the grid .

This is wat i do .

Oh really? It's that simple?
Mind linking what charger you use?

I use a victron ip22 model.
But i use 12 volts systeem .

You need a 48 volt charger .


Than again .
Cheap solution is really a Victron 48 volt multiplus.
You have a good charger and a inverter .

Its almost the same price for a good charger only with a high charge output .

This is the reason i do not go for a expand delta 2 max or other units like that.
The moment you need more you have a problem..

Amazon has 48 v x 7-10 a chargers for <$50. I use one for background charging from the grid on long stretches of rain/overcast.
