With experience on hybrid inverters with 500v max, has anyone try close to 480v or more VOC installation?

i have successfully done 440v on a 450v max voc. It worked. Then i did 468v on 450v, hoping the very long wire will probably sag the voltage to 440v, didn't work. Inverter displayed 448 to 455v. And an awful sound was coming from inside the inverter. I had to remove one before it stabilised. Verdict : you can get close to the max voc, but dont cross it.

Good evening gurus in the house,

I have been using a set of 8 units of 240W s with the following properties: Voc=37v, Isc=8.2A
I just bought additional set of 4 units of 240W s with the following properties Voc=60V, Isc=5.2A


How best will they be connected seeing that the large voltage and current difference between both sets of s.

Thanks as I await your responses.

Capacity test still ongoing

And how do one you?

Doing a battery capacity test now.

I think you should get a separate CC as I don't see how you can mix these s and get the full efficiency out of them.

Thanks for the response. This expected setup will likely hit 490v for the 500v max VOC Welion inverter.

Quick question, please

Are 4 units of the standard used 250w poly Canadian solar s enough to charge a 220ah tubular battery during the day and still carry max load of 200w simultaneously before sunset using a PWM CC?

For someone looking to buy a new tubular battery at the range of 250-300k, what’s the best lifePO4 alternative for around the same price even if the price is sightly higher?

I look forward to your contributions. Thanks a lot

Valto to buy a small lithium battery within your price range (24v). Get an external charge controller with sachet inverter for your system. You can also buy a hybrid inverter to go with your lithium battery and you are good to go.

So at least 80ah in the used battery.

Still going

Call if interested in the prag inverter and 2.5kwh battery. Used.

I don't have the money for a separate CC since I am using an MPPT for my system

How did you check it from their website

Call Yemi 0805 two one 5447 one. FYI, that is not me, just someone that I know still have some in stock. And they are original. I bought some from him recently and I checked the serial numbers with Jinko website. He is also a highly recommended installer based in Ibadan.

I've done close to 450v

50v by 9 in series

Don't Buy Lead acid in 2025 abeg..
We just replaced a Lead acid with this

It only managed 52,369AH, approximately 261 Cycles less than 2 years e don degrade to 10% capacity

Now we have installed 3.6kwh with 1.5kva Hybrid

Where did you buy the Haisic battery from?
I need the 48v(51.2) or two 25.6V

HeavenlyBang:


What inverter are you using now?

bread from hinen with service center at ikeja.

Recommend 5kwh 200ah lithium battery that I can get in the market. Good quality ones

Just checked out Hinen's models. I like what I see.

Hi House,

I'm looking for your opinions on Haisic battery systems for backup power, as I'm not going fully off-grid due to landlord restrictions on solar s. I'm on Band A power, which is mostly reliable, but we can experience outages of 16+ hours during rainy seasons.

My peak load is under 400W (excluding my fridge/freezer and a 150L Thermocool, which are currently off my 12V 105Ah inverter system). My total household consumption is around 700W according to my prepaid meter. I'm aiming for at least 14 hours of backup to get through the night with the 400W load, then I can use my generator to recharge and power the freezers.

I've seen a Haisic system d (though I'm relying on European specs due to some deceptive local marketing). The 24V 300Ah system costs ₦1.250m.

My main question is about system voltage:

Stick with a 12V system (e.g., Haisic 12V 280Ah for ~₦650k)?
Go for the Haisic 24V 300Ah system at ₦1.250m?
Or, is it worth waiting and stretching my budget (around ₦1.3m) for a 48V 5kWh system? I've read that jumping to 48V might be better in the long run.

How far bro. How I fit buy this inverter?

Haisic 12v 280ah is about 460k. 24v 280aH is 800k.

Another fear I have is that the 24V system is too closely coupled. Failure of either the inverter or the Battery may mean I need to do some gymnastics to either connect a new battery or inverter to the stack. Of course, the main attracting factor is the price of the system

I am aware. I am planning to buy both the inverter plus the battery. My current inverter and battery setup will be going to someone else.

I am replacing both the inverter and battery whichever option I take.

Haisic 12v 280ah is about 460k. 24v 280aH is 800k.

Hi HeavenlyBang. Morning bro. Back in 9ja and want to purchase the setup this week for a final installation on Sat. However I am still struggling with the issue of choice of battery. I have my eye set on a Felicity rated 7.5kwh 48V LiFePo4 at a decent price. But after doing a quick review research online, it appears some Felicity are known to not give 100% of their rated capacity. Please I need a final guidance from you before I go ahead and commit to a vendor today. Also going for a Growatt 6kva with Wifi monitoring and Jinko 620W s. Thanks.

SRNE don dey really dey crase.

Their 3.3KW inverter I bought for 370k last year is now 495k.

1.5kw is 320k.

How much come be 6kw Growatt abeg.

Bro, buy any battery from a decent brand that fits your budget. We've been on this for weeks.
