Normally, a functional BMS ain't supposed to allow you drain the battery to such extent

yes the bms hasn’t been activated yet. After the first shut down I tried a certain time to discharge it fully again it tripped the Bms lvd without the bms going off.

It was just a one time thing to activate the bms.

Hello house, please i have a 2.5kva indian inverter system that has no settings for Lithium battery, does that mean i wont be able to use lithium batteries with the inverter?

Also, it doesnt have any manual settings to change or adjust the voltage since the preset buttons is only for tubular, gel, sealed lead acid batteries only

Half bread is better than none. Use ur felicity CC to charge the battery. Ur inverter can charge the battery via AC though it wud be slow, most bms wud stop the charging once its full (my experience using afripower with a Sako battery so confirm same wit urs if not u wud av to manually switch of charge when its full). Main issue though is ensuring u manually switch of the inverter once battery gets to its recommended minimum so u dont drain it completely.

is it really 200km per charge?

It depends on a lot of factors:

1) Battery size and age
2) Motor size
3) Weight on ebike (the bigger the load on the ebike, the lower the range)
4) Terrain (hilly terrain drains batteries faster)
5) Type of riding (full electric or pedal assist mode)

That said, the type I got, different from what OP advertised, came with a 10AH 48V that was good for 25km on full electric and 30km on pedal assist.

I've long upgraded this battery to 30AH for crazier riding. E too sweet

Are there ebikes with range up to 200km? Yes, of course.

Is it what the OP is selling, that I can't tell.

Because of rain and cloudy season see what a 10kwh panel can only produce all day. 😢😢

I don't know about external charge controller but most hybrid inverters would wake a sleeping BMS

My Bread inverter did when I first drained battery to zero to activate the BMS.

Everything went off, both battery and inveter, the first sunlight the next morning immediately turned on the inverter which then waked the BMS.

Ah! Good to know about Bread inverters.

You can use it.

What you need to check majorly are:

1. Charging voltage float and buck (depending on which mode you choose gel,tub,SLA each has different voltage at the above mentioned parameters. So find out which option will keep you within the safe limit of 27.5-28.8v)

2. The charging current (averagely, it's usually 20A confirm if you have a toggle switch to select the charge current (select the lowest if possible)

3. Low battery cutoff voltage (most Indian inverter has LVD at 21vdc, so you will need a way to control the discharge)



If you can control this 3 parameters, you can use any Indian inverter with lithium batteries.

Not only Chinese inverters are lithium compatible (the only likely advantage you may get is that Chinese inverters will be able to push in more charging current)

For ur nos 2, we know Indian inverter are optimized for tubular batteries with their low charging current but why now choose the lowest charge current instead of the highest seeing it's lithium we talking about here?

You rely more on an external charger.
It's also subject to battery capacity too.

e better make this owner just respect him battery Ooo. Let him just rely on his charge controller Ooo. He need understand that We can offer suggestions, but we no go follow am carry the wahala. Most times, na hybrid inverters dey support Lithium battery well enough.

Voltage is voltage and current is current. As long as the charge/discharge parameters are within spec for lifepo4, I don't see what the issue could possibly be.

There is no way he can give you a definite answer to that question. Range to be covered per charge depends on the battery capacity of an ebike. Range is also the most expensive in an ebike.

Most bikes you see around only have 20 - 50km range , because they are mostly equipped with 48v 20ah battery, some of them even come with lead Acid batteries and all these bikes are cheaper too, because battery is the most expensive component in an ebike, it accounts for 60-70% price on an ebike.

The ebike I advertised has 52v 79ah Samsung cell batteries, that's why it's able to cover 200km per charge. If you see any bike with 20ah, 30ah battery claiming it can go a range of 200km, you should know that's a false advertising.

Mrreed:
Good morning chiefs, these are what I have at the moment and their prices.

All with JK Bms

24v 7.1kwh with 200a BMS Rept or hithium cells @ 840k ( metal box)

Which is better Rept or hithium cells?

I am going lithium for the first time

Good evening

Please who has experienced charge controller giving extreme high voltage to battery when battery is full? The old Powmr controller with 2 Jinko 590w panels in series connected to it, gave a battery output voltage of over 39v on a 24v system triggering inverter error code 3 and 8.

Has anyone experienced this issue of controller giving out extreme voltage when battery full? What is the way out of this?

Thanks for your reply and happy new week to you.

Mine does this but it also results in the breaker that I installed between the charge controller and the battery tripping off.

Have you installed a breaker between both?

Maybe I don't get that code because of the breaker between the CC and the battery, but it often causes the battery to be undercharged by the end of the day, if no one was not at home to check and reset the breaker after a while

It is highly recommended for safety reasons.

Sorry that I did not answer your question in full

According to a summary by AI: "For a user prioritizing the longest possible lifespan for a stationary energy storage system, Hithium's high-cycle-life cells may have an edge. For a user seeking a well-known, reliable brand with a proven track record in both EV and ESS, REPT is an excellent choice."

Still torn

What is the experience on this forum?

Except that REPT is an older brand, which is better largely depends on preference. Hithium for instance, quotes longer cycle but no one has used it for that long. REPT on the other hand quotes slightly shorter cycle but also in excess of 6000.

Just found it's cousin in my friends house. It's a generic charge controller that different companies stamp their brand names on it.
Looks and feels subpar. I Will observe performance, though sun has been very absent coz of rains.

Good evening,

I find myself with a peculiar but pleasant problem- Redundant excess power.

I don't use an AC unit, no plans for that now, am looking to utilize this energy towards cooking( help cut down the LPG bills )

Am seeking recommendations from anyone currently using their setup for cooking on energy efficient options available.

Inverter is a 4.2kw sunfield hybrid.

Thank you!

well except you buy those energy efficient hot plates, which most times, ain't as good as your conventional cookers, you could try selling the excess power to your neighbors.

if you must use a hot Plate on your Solar, would suggest you look into Induction Cooking Plates . Hopefully your inverter can channel most of it's power from the Sun to the cooker so as not to stress your battery. One advantage of hybrid inverters.
Still on still, be careful, na Hybrid you dey use and dem sabi spoil just as Chicken sabi die for poultry business.

To stress your battery less, you could consider Cooking with Solar only when the Sun is at it's peak. That's if you end up using Solar for Cooking.

This is what happens when we don't access our energy requirements before on-boarding Solar.

Your Inverter will be fried instead.. Use better brand of inverter minimum 6kva for cooking.

Not really.

If you think that way, then alternative energy is for folks with fat bank accounts. This was not the origin of this thread.

If some of us wait till we have it all together we would never get started, and ultimately pay a high cost trapped by the ever increasing decay in this system called Nigeria.

Thanks for the hint. Will go research on the induction cooking plate

Dam5reey:

For a 4.2kw inverter, cant it handle a cooker that consumes maximum 1.2Kw? That even drops to 400w intermittently?

Nice move, but keep in mind that you should not exceed 50 percent of your inverter capacity and I'm guessing you are using lithium battery with enough panels.
A 1500w cooker should be your priority or induction cooker that you can regulate to output 1000w to 1500w.
I normally use my 4.2kw Powmr inverter to power 1500w water heater, 1 hour daily at peak sun hours.

There is a 63amp breaker, but doesnt trip. So na to dey monitor and trip off before full charge if i am to continue using it?

buy a single burner toks halogen electric cooker(consumes max 1600w), minimise other house loads when using the cooker. your inverter can comfortably carry load lesser than 3kw..cheers.

you seem to have misUnderstood my comment. Never asked you not to use Solar, what I meant was - if you had accessed your energy needs, you would have known if you needed a Solar capacity of 1kw or 3kw or 10kw.
mind you, should you need a 2.5kva inverter system, and you went for a 10kva inverter system, that inverter hardly would be efficient enough because the load would be far below it's rated capacity.

it's like someone whose monthly data usage is less than 2GB going for an MTN 20GB data plan, then few days to expiry, e come dey download any how, dey stream any how, dey find ways to exhaust said data WHEN there wouldn't have been need for such wastage had the proper data plan been bought
