Energus Tiny BMS s516 4-16S 150/750A version

[felixdennis]

Hi,

I'm looking to build an emergency portable solar power backup system. I'm thinking:

1. 1kw solar panel
2. 24v
3. 8x 3.2v prismastic cell 280ah
4. 2-3kw inverter


So far, I'm looking at different BMS solutions. Will this work for my purpose:

Specifications

• Series cells: 4 to 16 (6 to 16 for LTO)
• Cell voltage: 0.80 to 4.50 V
• Cell balancing: 150 mA, dissipative
• Discharge/Regen current peak: 150 A**
• Discharge/Regen current sustained: 60 A**
• Charge current peak: 100 A**
• Charge current sustained: 30 A**
• Discharge/Charge/Regen current: 750 A*
• Interface: UART (USB / Bluetooth / CAN)
• Up to 64 channel temperature sensors (available in Energus Cell Modules)

* - with external relays and current sensor
** - given that BMS is mounted on cool metal surface.



Questions:
1. It seems like sustain discharge is 60A. This is about 1440w correct? Can I run a basic welding machine on this that works noramlly on 110v/15A power. How big inverter should I choose?
2. How is this BMS compared to Chargery? This costs $280 vs chargery which is $140 for BMS16T
3. Should I shoose 8s or 16s? Is 16s required only for 48V system?

Hello, Did you ever go ahead and get one of the Energus BMS units? I'm thinking strongly about getting one also. European Quality looks good.

I don't know a ton about it, but I've been curious about it for a while, looks like a quality unit, very feature rich, very enticing option, but it hasn't got much attention on this forum so far. Definitely not a simple plug-n-play BMS.

I believe @Steve_S may have seriously considered it before choosing the Chargery, he might have some input.

Thanks for the reply. It looks like it was designed for the E-Bike trade, but also adaptable to off-grid solar use. I'm a little antiquated on all of this bluetooth and raspberry control of these devises. Not sure how I would be able to program the Energus BMS. Thanks, Martin
