Thinking of getting an Inverter System, Pre Wired - Off Grid. Any suggestions?

[Greg Burton]

If I decide to go the 48v route, how would I wire the 8 - 24v batteries that I will be getting? Thanks!

are you batteries 24v each ... or are they 12v or 6v?   I would wire anything you get in series if at all possible as long as the amp hours meet the needs of your loads.

Each battery is 24v and I have a total of eight...Thanks!

bur1196, just to be clear .... 

you have 8 @ 24V LiFePO⁴ with a BMS for each pack of batteries....

or have I got this wrong?

Yes...I have eight 24v batteries:

Battery 1 - 24v
Battery 2 - 24v
Battery 3 - 24v
Battery 4 - 24v
Battery 5 - 24v
Battery 6 - 24v
Battery 7 - 24v
Battery 8 - 24v

How easy to wire all eight of these to 48v...

Do they all have an individual Battery Management system...

BMS â€" Battery Management System

A BMS (Battery Management System) is essential in a Lithium-Ion battery system. This device manages a real-time control of each battery cell, communicates with external devices, manages SOC calculation, measures temperature and voltage, etc. (see key features on the right bar). The choice of BMS determines the quality and lifespan of the final battery pack.

I would check with manufacturer to make sure that 48v setup would be okay for BMS or other controls in those batteries.

Westbranch: Yes each individual battery has bms...

ClassicCrazy: These batteries are perfectly fine for a 48v or more setup...

With the BMS you should be able to set the Classic for 48 V and charge them in parallel...
