So, I have been researching batteries for a while and I think I have settled on the Pylontech Us3000C 4.8KWh. The main reason for this is the modularity of the system, as space is a little constrained, but with these I can put them in the eves of the converted barn we live in. I think I want to pair this to a Victron MultiPlus-II 5000VA, but maybe the Quattro 48/8000. I am not sure...
My plan is to eventually get 10 batteries to ensure capacity during the winter months, but I plan to start with 5-6, 6 Batteries will give me around 27KWh usable when fully charged as I understand it.
The general idea is to charge the batteries up during the night on a cheap tariff, and then discharge them during the day (solar is not currently an option)
Now, this is where a gap in my knowledge appears, I don't know a great deal about inverters, regarding how fast I can charge the batteries etc
I want to be able to charge them at 7KW, for a period of 4 hours, is that achievable? I am on single phase I also want to be able to power the house from the batteries when we have a power cut, ideally automatically but I will settle for some kind of manual switch over if this is not possible
How long can they sustain a load of say 3-4KW, will they be able to do this for 3 hours at a time?
Is there anything else I need to consider? I don't suppose anyone knows of a good installer in Kent do they?
Many thanks
