So, the question is, can I use 24v breakers on each battery and then serial connect them all. wont that breaker always “see” less than 24v? wont that breaker need to extinguish <24v arc? if all breaker work together?

Agreed. Battery Size?

The tranfer switch is clear to me. Not sure I understood how to connect the new main breaker panel to the old main breaker panel?

Hi Guy, Please be careful. Making a Lifepo4 4S1P A123 20ah Car battery. By mistake shorted with the wrench when tightening the Negative terminal Video

Hi @doctorcupcakes , that Battery Case looks very nice. Looking to build something similar. Do you know the dimensions?

My first though was going out through a Breaker like (picture) that, but AMP Breaker is not enough .

Hi Guys Anybody has experience with this Hankzor balancer plugged 24/7 ? Ive heard that capacitor based are not recomended 24/7, was wondering about this one link

Hello, Can you provide the model number?

UPS is one example

@snoobler Thanks for your answer. If I decide to DIY, will this work: 4S 10P Pack cell: LIFEP04 32650 3.2V 5000mah cells have a MAX PULSE DISCHARGE (10 SECONDS): 50A (10C). Without a Bms since the alternator will not charge aboce 14.5 volts. I live in the tropics, dont need cold disconect...

Hi Guys, Im in the market for a UPS 12Kw. Any recomendations from past experience, reliability. Need to Backup 15 Tons of HVACs. So Probably Low Frenquency transformer with 3X Surge Capacity. In my area, the Grid is very unstable. Looking to Protect the 5 mins between the Grid Going down and...

Well, Well, I Stand in between you guys. @sirslayer I would take the max at half the rating. 6awg = 150 A I have tested extensively silicone 8 awg up to 150 amps, and I would not go past 100 amps which is half its rating. It gets too hot, meaning resistance is High. Ohms Law. In short runs <...

Hi Guys, I recieved my Empty Battery Boxes (ABS) from Alixpss and everything is fitting inside nicely, Lifepo4 GSP 12v 50Ah. Was wandering which Adhesive is best for this application?, to shut the lid permanently and make it unserviceable. I noticed Battle born using what looks like Silicone...

Thanks for the feedback. As a separate topic, I’ve been wondering exactly this . Do you have literature to back this up?

Hi, Can anyone recomend micro Hydro turbines. 100w to 1000 w Reliability..? Thanks

Thanks for the link. Can you give us an update after 6 months with the cells? Voltage sag? capacity?

LifePo4 Uses same voltage than Lead Acid. Im installing a APC 30KVA now, with LFP 192 Volts. No BMS exists for that. Fuses and Breakers. Worst Case, the high Voltage Fries the Cells. No Major issue to surroundings.

@Dzl I still wonder where you Rank Seplos BMS Now a Year later, with all rack battery & BMS, I wonder if seplos BMS is on the Higher end Alternatives? or why not?

Battleborn guidance is: 3.4 v per cel is recommended for Float charge. They say that it will balance the voltage and will not move current. They will honor their 10 yr warranty with the float charge.

What about this one: Will it have the same Breaking Amps as a T Class fuse?

Hi Guys, I have a operational issue in a beach house (used sporadicly over the weekends) where the post Transformers dont seem to have enough capacity for the two houses in the complex. Wanted to know the best way to supplement and fix the problem with AIO inverters and Batteries. two houses...

Exactly my point. Im suggesting that Maybe, just maybe, this time Mpp Solar sourced this inverter from Deye.

Yes, that’s what I Thought. The MK line have 0 transfer time. It says it’s double conversion. Im actually looking into the MK line or the LVX6058 to use as a UPS backup for large loads. running solar to offset the cost. Im struggling with how to calculate the kwh battery needed ...

@smoothJoey Could you share pictures of your build?

I dont recognize these 3?

@Hedges Hi Can we expand on that? That was exactly my question. And that was exactly what I was thinking. So, since the breaker/ fuse would only see the volt to where is connected. Im asking because im looking into finding a solution to few problems problems: - LFP have very low internal...

which inverter you’re using? it allows you to change in % or voltage? voltage is a problem for LFP, never know true SoC does mpp solar allow to change based on %, shunt?

Hi, you mean ABS cement?

Anybody has used this meter? Powerline Analyzer SHARK 100 Link
