Recommendations for Quality BMS for 16s 45kwh Off Grid Build

[JIMMY]

While the Covid-19 lockdown here in Queensland has delayed the PV install it gives me a bit more time to finalise the build specs on the rest of the system.

I am fairly happy with the rest of the setup but am still deciding on the BMS I am going to use for the battery pack.

It needs:

- 16s
- 200a charge
- 200-300a discharge
- Remote monitoring via internet
- Low temp cutoff is not needed (12c / 54f is coldest recorded historically)

Being that the property is on an island and over 2 hours driving along a beach at low tide from the nearest town and another hour after that to a regional centre for parts etc reliability is critical.

What would you recommend?

Thanks in advance!

PS.

I am looking at using 2 Growatt SPF 500TL HMV-WPV offgrid inverters to do the heavy lifting.

What's your budget, and what sort of cells are you planning to use?

The Chargery will do what you want however the remote monitoring is a bit sketchy. But does work.

Also look into Batrium and 123SmartBMS they are quite a bit more expensive but look a good product. For those kinds of loads I think you will want a relay based model.
