Unfortunately there is no known brand as PZ, I found out this website with their office in Benin City, Edo State https://www.pzenergytech.com/

This is just a rebranded Voltronic Entry Point Inverter. I'm afraid you might not be able to change any settings on the unit.
Please contact the seller or the company via that website to provide support to reduce the charge rate.

That PZ Inverter looks like Grovolt Amuma Hybrid Inverter, many clones everywhere.

2x 1hp pumping machines
3x Laptops
2x 50W Extractor Fans, turned on at Power Room Temperature above 35 Degrees Celsius, turns off once temperature drops to 30 Degrees.
ETC. (Phones Chargers, 4 Rechargeable Wall Fans, Others)

NOTE: All these I have tested real time on a sunny day and I was good.

Grid is available but only turned on automatically by a contactor powered by a Photocell sensor on really cloudy days. So i could say that i am partially OFF-GRID.

All Water Heaters and 4ACs are connected as smart loads and configured to turn off once Battery SOC drops to 50% and no Solar Power.

DIY battery packs are great, but I like data/communication and i am yet to see any assembly that have included RS232, RS485, CAN, and etc ports. Bluetooth options as integrated in most DIY packs is great but is limited to your presence near the installations to be able to get data.
So I intend to re-use the casings I have now in the future if i eventually need to replace my cells.

JK BMS now have data communication and you can link them all.

is this brand still available?

There is nothing wrong tubular batteries. I've a friend who has used his for 5 years now and they are still waxing strong. He bought them from the right source and he's baby sitting them as well as derating the capacity he's using...
Some people love buying products they're familiar with while some like going for new innovation....
It's a matter of choice.

In small capacity say under 6 batteries, I see nothing wrong too. But if you really need energy to require up to 20, that's where I'll recommend going lithium. I've seen cases of this type of system dying way before their time due to issue mostly related to charging. Most of these large banks like this miss out on proper charging. Going the lithium route would've been a better alternative when you need energy this huge.

Have anyone have a good metal fabricator that can build custom designed DIY battery box like those in this attached images?

Impressive I must say. Been following your setup for quite some time because I'm trying to use it as a benchmark for my own off-grid solution in a couple o' months. Thank you for listing your load consumption. It was very beneficial as we share almost the same load setup; just a bit different quantities as follows
1x 2HP standing a/c
1x 1.5 HP split
5 x 1HP split
7x chandeliers
No desktop machines
5x 15Ltrs w/heaters
about 200yards of LED lighting
No electric burners (gas only)
Kitchen hood/Smoke extractor
Electric gate and fencing
1x 1hp pumping machine
1 water pressure booster
1x washing machine

Everyother thing remains quite (almost) identical to yours. Pray tell, if we swapped loads, do you think your setup would conveniently carry mine? If you had my load setup; what would you add to your inverter setup to still maintain power autonomy without worries? Thanks in anticipation.

Anyone who has build a Battery Bank with this JK BMS should share Tech Specs and Pictures please. It must be housed in a well fabricated metal casing.

Perhaps you should do an energy survey first to know your peak energy requirement.
This is what I did before deciding on the capacity of my setup.
The tool in the attached picture can help you or simply install a smart meter and study your consumption for sometime.

Who did the audit for you? Are they available in Abuja

I did it myself, perhaps some people are in Abuja that does it also.

Chat me up. I've seen a metal fab company close to my area before, although I've not used them.

You are balling... 😊

My sachet inverter when pulling about 600va AC load, draws about 1kva DC power. That's about 60% conversion efficiency. Ambient temps was in the high 30°s though.

Has anybody actually measured their DC to AC conversion efficiency? I'ld like to know what they got. 🤔

AEDC will so hate you right now! 😌

jonescosmos:


The picture has all the details. But since you asked.

PV is 15KWp (16x 600w Canadian Solar Panels. 10x 540w Felicity Solar Panels)
Inverter is Deye 8KW EU Model x2 in parallel
Battery is Felicity 15KW x4 in parallel though capacity test topped off at 13.5KW. So I have 54KW Battery literally.

Many thanks for your reply. I'm going to monitor the consumption over the next couple of days and get back with my findings with concentration during the hours of 5pm - 10pm. Everyone will be at home and in consumption in full gear. Too bad that would be when sunlight is already out.

What most people always ignore.. what type of batteries?
those inverters have poor efficiency.

Advice needed!

The DC component of my solar installation has been sparking and melting of late. Sometimes, it stops charging altogether, until we reboot the system. We were told to replace the unit, which is 63 amps. Now we are contemplating getting the 100amps or 123amps...is this ok?

Again, what is the best brand to go for; the current one we are using is Schneider but it seems fake. What better brands are out there?
