Yeah why not. If money isn’t an issue then I don’t see why not.

Only if money isn’t an issue though lol.

Actually got me thinking.

I am on MBB and Powerforum. I legit haven’t seen a single post of someone complaining about an error or something wrong on the Victron. Granted only been 2 years now almost but still.

Sunsync, Deye, Pylon, Axpert, the clones etc. there is always someone posting something. Could just be because few buy Victron also who knows.

Victron is like Apple. Nice ecosystem and it just works.

Yes, it used to be worse. Now its only double the price of the competition.

Any good deals on a 200Ah lifepo4? Considering the 100ah are cheaper now it seems the prices of the 200Ah are still high.

12V

that is A hard one because I don't always trust the 200ah claims on some off the 12v batteries

To add I am looking at better brands so that I am able to add on, need it for a small system for fridge, lights and TV.

Exactly, there is a flood of them but the specs, specifically the cycles, current discharge are dodgy.

I wouldnt worry about mixing brands.

 

[TheChamp]

I wouldnt worry about mixing brands.

I guess, they have BMSes so should be able to sort themselves out. Alternatively I could go for two 100ah but it works out expensive.

Not too worried about the mixing, mostly looking for good cycles and a decent discharge current, for the fridge.

How about a 300Ah?

or 100Ah?

1 x 100Ah should be able to handle a fridge.

I would go 100Ah. That way its cheaper to upgrade to 24V or 48V later. Just need a balancer:

I have a suspicion the fridge gets very close to the max 100A at startup, not very efficient so there is a slight dimming of lights when it kicks in, with the TVs and lights, the 200Ah is the comfortable choice.
