I have used both JBD and JK BMS - JBD BMS were originally targeted at medical devices so quite rugged build quality and plenty fail safe features built in.

If you want a pro product with plenty flexibility, ability to talk to inverters via RS485, up to 2A active balancing then choose the JK BMS - if you have multiple BMSs in your battery bank the JK also switches between BMSs far better and smoother than JBD.

I say the JK BMS is a pro product because it does not forgive wiring mistakes and also needs a special procedure to wake up the BMS - once you can handle these two aspects you are set to go forever.

Seplos too is a good BMS with active balancer and comms but very failure prone in real life use (we are told there is a bad batch with defective parts released into the market)

I would rank the Dalys and ANTs of this world behind all these BMSs above - typically these cost more and are more quirky but I have yet to see any reason to choose them over a JK or JBD BMS for example.

I have attached screenshots from my JK BMS (current favorite) and JBD BMS respectively - as you can see they each achieve good results and keep your pack happy - the JK is the better value product of the two in my opinion.

Currently use JK with 2A balance current. Two years and it's still kicking

Used it in both 24v system and 48v. Pretty great BMS

The late response is no problems at all. As a matter of fact, I was just about going for the inverter and I thought I should check here one last time.

You got me smiling. I hope your buddies bought you a bottle of wine for showing them the road?

I must say that I'm caught in the same net as your friends on this inverter choice. I see a couple of people here saying the separate setup is better than the hybrid inverter for the fact that once the hybrid is faulty, everything goes out the window but for the separate setup, you can still salvage either of both CC and the inverter. Although, I considered the chances of both the separate setup also getting faulty at the same time - or even worse. I decided to JUMP on the bandwagon of "team separate" o.

I'm actually going for the 1.6KVA Pure Sine Wave. Wanted to go for the 2000w but the CC specification says it should not go beyond 1440w (which I believe I still have gone against if I go for this 1.6KVA) or you will have to buy either two 60A CC or an 80A which this particular seller does not have. I guess this is where the hybrid outplays this "manual" setup auto detection and adjustment and less cumbersome. I do not intend to use it for more than the things I have listed. In fact, when the time comes for upgrades, I'm just going to overhaul everything if I have familiarized myself with one or two about solar energy.

Thanks for the time and advice Sir. I honestly do appreciate it.

But is there anything else you think I might need besides these?

Xmen149:
Guys,please whom has used Felicity charge controller here,80amps.

Will it pick system voltage first and come on on battery before solar connection.

Or solar and battery must be present(battery first) before it can come on.

Urgent!..anyone? Bcs am beginning to think the supplied device is defective

bbally:
Hello bro, I will suggest you try out new pure sine wave inverter that kiekie just advertised instead of ordering from AliExpress and waiting for 3weeks. it has 2000w(1000w) and 2400w(1200w) in 12/24/48v variance.
I just got one from him too and as far as av tested it's good and the wave was smooth.

uniqUN:
Oh wow. I wish you had mentioned it earlier. I already ordered for it. Nevertheless, since you recommend him, I might still get to buy something from him moving forward. Thanks for the reply.

Is Growatt SPF 5000 ES 5kVA inverter a good inverter to use with DIY lifepo4 batteries?

I was considering a victron quattro 48/5000 but I can seem to find any incountry and the price is too high?

Which is the next best thing after Victron to use with lithium batteries? Next best thing.

olopan:
Have you got a range of energy logger with high CT rating ....... interested in price range

Let's assume your budget no dey shift and again your looking to make your equipments future upgradeable and expandable

1. A 3KVA 24V Hybrid Inverter - @Iygeal has one at dirty cheap price, being a season member, i am sure some months of performance can be guaranteed 180,000 ....... Future expansion compactible

2. 300W solar panels x 4 pieces for basic, 1800W is needed ideally while considering efficiency of solar panels and your loads been active 232,000 ... Or you can try the Tokunbo panels, if you into it. ....... Future expansion compactible

3. Flooded lead 12V 220Ah battery with 2 year warranty (Different varieties abound) - 240,000

At this stage now, you approximately have 48,000 or less

4. Battery rack, Solar PV cables, AC cable (shorter distance <5 yards, roof sealant, aluminum profile, mounting accessories all should finish the balance

5. With no "balance of system" i.e. SPD, circuit breaker, et. cetera needed are not yet considered

6. With a service charge for your installer and transport from your seller to your abode.

IMHO, you will need more than 700k to complete this job, but then again if you can mount or do it all yourself ......... then you save at lot of cash.

BTW a more cheaper option is to swap the inverter to hybrids like schneider electric 1500VA with PWM inbuilt controller, it will free up some cash for you, but it is not really future load expandable but you will at least have power at the needed time which is now.

olopan:
Please if you are seeing this and we spoke sometimes late last year on your solar project in Abuja, i didn't forget you ......... in fact your contact was misplaced when my phone was stolen .......... please try to reach out again

adrusa:
I'm not sure what you are describing, but the good practice of installing charge controller is to connect the battery first and solar thereafter.
As for Felicity CC, it has this quirk that I later discovered, if there is no solar, the CC sleeps off, no sign of life. You need to tap the button on it for it to come alive. Once you connect the battery, the voltage will be automatically identified. You can then go ahead and do the settings.

tsiriman:
Hello,

Please what is the best DIY BMS to buy, I have been researching JBD and also Seplos for the 16S 280Ah lifepo4 battery bank I am planning to build.

What has worked for most people here and which is the best to go for?

JUO:
worked for a while and stopped. Replaced with prag which still works till date

ojeysky:
Growatt is very good, if you can get Deye that is much better as well.

FireTheSun:
If we judge by Popularity and spread of use, l think the Daly BMS is the best and most used .

But they can be pricey, which ofcourse, you would expect from a product that have stood the test of time.
I also think they are about the easiest to connect.
A Noob like myself, connected Two units of 200A Daly BMS to 32 St`rings of 280Ah LiFePO4 Cells (16S 2P) and they without any hitch!

But there appears to be cheaper variants of the Daly BMS as well though l will rather use the "original", if l can afford it and that is a personal policy.

Edit: reading later, what @NiyiOmoIyunade wrote and knowing that he does this for as a Business, l will defer to his opinion since l have not used the other variants and his experience will be very valuable in that regard,
so far, l am enjoying both Dalys, without any issue with them

felaliveson:
Hello gurus, I’m planning on getting a lithium battery powerbank 500watt inverter with 120,000mah lithium battery inbuilt … i was told it can be charged via 18v 200watt solar panel

My question is that, will it be a good buy Also does it mean a 12v solar panel can not charge it…. Also if I decide to switch my solar panel to lead acid battery with 12v inverter, can the 18v solar panel charge the lead acid 12v battery ?? Reachable via 08065..316307

Buy Lithium battery or keep your money ....avoid lead acid battery like plague. it is like using Symbian phone when android can serve better plus lead acid are like a drain on the pocket now as most users have to replace their battery every 3 year or less where Lithium can serve you for up to 10years. For your intended need, the Lithium battery will be just fine Sir. I assemble lithium battery as powerbank for laptop and inverter battery for homes and the customer review are amazing to say the least.

Namzy:
Are you sure lithium ion can last for 10 years?

Fapemz:
Sure Sir, a good example of that is the INEC Blue Battery that introduce many of us to LiFePo4 Battery. Some are still using them till date. They were imported for INEC voters registration of 2010 if memory serves me right!

IYGEAL:
Still up for grabs
