TBB Power has been popping up lately on the forum, do you have info on how to get a distributor?

I thought growatt & srne were some kind of voltronic/axpert system albeit modified.

I went from Growatt to Sako. My experience is that my old growatt charges better. The Sako is still serving well though. But I only wish it would give me the growatt efficiency which I experienced.

I will check if there is a firmware update for the inverter.

Off course, MPPT pass MPPT....
Some MPPT waster so much power during conversion, because the Buck converters have different grades.

Growatts na better Soup... I have tested some Hybrid MPPT and was surprised to see power wastage.

Dam5reey1:
Firmware update on top of unofficial Voltronic OS..

Its like expecting latest Android OS update on generic android phones.

Hello house 👋🏾

I have a problem with my 8kva felicity inverter and my installer isn’t even coming to check it.

It trips off load all the time. I bought 8 unit of 600W panels, only 7 was connected, 1 was broken. At 100% capacity, it supposed to give me 4.2kW but I know that it’s not possible. I’d be receiving 3.5 - 4kW but I don’t get up to 500W total wattage from it. The 4 wet batteries are starplus products.

Now it doesn’t work effectively except I connect it to NEPA, but I should not be on NEPA because I’m not paying for it. I was even disconnected from NEPA which is very much ok, my solar energy system is supposed to be sufficient for me without NEPA.

The installer has refused to show up. What do you advise?

I’m in Lagos, in case you suggest another experienced installer and you can share their contact with me.

Erroneously assumed, mppt were generic across board until I started observing that my Sako is not pumping as much juice as anticipated based on my previous experience with Growatt. The Sako has an mppt input range of 90v - 450v while my growatt is 120v - 430v. It doesnt look like the sako mppt range is too wide or different.

Could this still be a potential cause of relative inefficiency.

Dam5reey1:
They are reliable, however, 30-400V MPPTs, are less efficient compared to 120-450V ones

Ferdiwar:
If the BMS came with a battery pack reach out to the seller/builder of the battery pack.

But if you got the BMS separately consider reaching the store for the password change chances are it was changed from 1234thank you, there's no information from the battery pack say the builder

brightk:
lol.. abeg how did u conclude the battery is discharging itself... let's start from there

mctfopt:
StarPlus is a low-quality tubular battery. That being said, I think you need another installer to check what the other installer did on the roof.

If the 8kVA is of the Felicity hybrid type, and the VoC of the solar panel is below 50V, the 7 panels should be connected in series. Before this is done, the installer should check each individual solar panel to confirm they are okay. You should get at least 2.5kW from this setup if positioned on the south-facing side of the roof, and the roof inclination is not too steep. The best roof inclination angle is one that is almost flat.

Yes, it’s the felicity hybrid type. Thank you, can you recommend a knowledgeable solar installer in Lagos?

For real?.. .. assumed all hybrid inverters cc will be mppts.

bbally:
Which area of Lagos are you? Give a call

Anyone has any idea on any good servo stabilizer, bought prag 30kva, and it got bad within few months, has anyone used himel or Mercury brand of servo stabilizer??

So are SRNE, Growatt official voltronic OS?

Please what's the difference. I got QASA 5kva wall stab. It has been a regrettable experience. The stab fluctuates so much that my ecoflow power generator's charging goes off and on. Makes clicking switching sounds sometimes. And the voltage delivery range is so inconsistent.

I recently saw prag and noticed "servo" was attached to it and I'm wondering the difference between them.

kristien4:
i dont trust wall stabs, they are way lighter in weight compared to normal units of same capacity. That clicking sound is the relays, while servo stabs uses a different mechanism, kinda mechanical . Google the differences. I intend buying the qasa 10kva normal unit, weighs 65kg, while prag 15kva wall unit weighs 30kg. That difference dey surprise me..

Pls house, any Sako major distributor in the house pls. I'm having issues with a 3KW sako inverter with random fault (3). When restarted everything seem normal until after some hours. I have observed for days and I concluded it's a factory fault from the inverter. Pls come to my rescue
