14s to get 48v?

[Jonisingt35r]

hello
im just started to build my battery, and looking for inverters, wondering if my cell count is right im going to build a 14s and charge my cells 3.6 to 4.0 therefore my bettery will 
go from 50.4 to 57.4v, do inverters tolorate overvolting up to 57v?

14s 18650 is probably the most common config and fine for a wide range of inverters. I have used Reliable inverters in the past but settled on AIMS for a more robust 24/7 usage. I think you'll find that almost every 48v inverter will be fine.

If you dont know what gear you are going to use 14s is the safest bet for sure. It fits 99% of all 48VDC equipment very well.

That's a good range. And yes, inverters go up to 57V just fine. And actually, most will do at least 62V. Remember, most battery based systems are based off the lead acid battery, and it's operation is 10.8 - 15V ("48V" system would then be 43.2 - 60V). And there are a lot of chargers that can go up to 64 or 67V as they have lithium batteries in mind as well.

Korishan.. what solar charge controllers go up to 64v and can charge lithium? U said there’s a lot.. I’ve been searching and only found the victron and midnite that can charge to 64v..

If trying to fit lithium into a lead-acid battery voltage range, 14s fits most all 48v hardware very well.

7s = 24v lead
10s = 36v lead
14s = 48v lead

I have come across a lot of equipment that accept higher input voltages as well… I am working with a 15s system as my EV batteries are in 5s modules wired 3 in series, but that does limit some options when searching for equipment. I have observed most of the most of the well know or commercial brands out there don’t have a problem with this. Victron is generally my first choice for MPPT Charge controllers, inverters, and DC-DC converters.
