Yes I can it but "never" Efficiently because you need like 600W for every 200Ah of battery and considering you want to use 4 batteries

600W x 4 = 2400W ideally
But in reality you might want to over size not more than 150% if using Tier one or 200% of charge controller if using tier 2.

All the above depends on your pocket, grid availability, and last aim of use etc.

Checked throught your recent post, if you have not bought that inverter I will recommend Growatt for you can handle over sizing too and sure will charge your battery with no stress.

Sorry about your inverter going bad but the scenario you explain feels rather weird to me.

The PV wasn't say energized like when the sun was up ....so power wasn't suppose to be coming in.

I have been to site with no PV disconnect for conventional charge controller and disconnecting the PV while operating " though bad" never had a fireback or otherwise .

My educative guess is that the PV input and BATTERY might have a kinda common bus .... So maybe on removing the cable some tiny strands bridge the +ve and -ve.

Just my opinion. .....

That may be possible but very unlikely. The sound was reminiscent of a capacitor forced to discharge.

What the inverter does now is produce a massive spark on trying to connect it to the battery. Sometimes it shorts off the battery. The sparks are big enough that they almost washed off the threads of the battery terminal.

Since the repair guys don't seem to have any clue as to how to fix it, I'd go take it back and try to feed it PV first to see if it would wake up.

What I have learnt is if the arc is too much something isn't right.

And from your explaination below, I guess you don't have a battery disconnect too

Just for the sake of when you have it fixed and returned, please kindly get them Disconnectors as to proceed with ease and enjoy your system

Do you mean circuit breakers?

Yes.

It happened to me when I was installing my new felicity inverter, gave off big sparks, at a point melted the lead of one f the battery terminals and one f the battery rack iron rod. My wife was scared. I made 3 attempts, similar event happened the 3 times, until I called an installer friend who put me through. First be sure the batteries are properly connected. My problem was I was moving from 24v to 48v system, battery connection is different. Be sure there is no short circuit. You can call an installer to take a look at the connections

Battery is a standalone 24V, inverter is also 24v.

Tried feeding PV and also experienced a spark. Took it back to the repair guys to try their luck.

So I'm on the look out for a 24V 3 to 3.5kva hybrid inverter which would preferably have a lithium profile.

I need opinions on which is better between Growat, iCellpower and Sorotec. I think my preference would be the one with less idle power consumption and less minimum pv input voltage.

Hi Guys,

Does anyone know where I can find a 48VDC or in lagos? I'm look for a cheap way to maximize/prioritize my solar use and want to use a relay-or combo.

I will set an under voltage relay to close when battery voltage is, at say, 50V and supply the coils of the or which will then close and supply AC to charge the batteries through the inverter, so as long as voltage is above 50V, relay(and therefore or) should be open and you are using the s to power your house. This should mean that you don't need to be manually switching of AC power supply to maximise solar.

The relay is easy to find but the 48 VDC coil or is what I have been looking for, does anyone here know how I can find one?

I'm also open to suggestions on easier ways to achieve this.

Why though?

Abdomox:
Good day all. I recently got two 220AH Luminous NRGT batteries (Tall Tubular) and my inverter indicates the batteries are full. When measured with voltmeter without load they tly read 25.6V.

But when I put load on the inverter, and put on like 5 led bulbs, the volmeter immediately drops to 24.4V. I'm surprised in the sudden drop in voltage.

Is this normal or there is something wrong with the batteries.

Inverter is Luminous Hybrid also bought newly

I noticed same thing about my Luminous battery. Though mine is a single 200ah battery, when there's load on it, voltage drops to 12.2v and it remains so for several hours. When there's no load, it jumps back to 12.4v.
Are you still experiencing this? Though mine never go below 12.2v even during long hours of usage.

Have sounded this clearly here several times...
Steer clear of luminous and mecury inverters, if grid charging is your primary charging source , especially if your are using flooded batteries.

Float is 13.7v and absorb is 14.8v, luminous and m3cury inverters arw notorious for poor charging algorithm, voltage and current. I wont be suprised if its sending out 13.8v as absorb voltage and 12.8v as float voltage.
Your batteries are seriously being undercharged, with resultant sulfation.

Best to buy an inverter with editable charge voltage settings, that way you are sure of sending th3 apprioprate charging voltage to your battery...

Lastly, hope your phcn voltage is above 210v, luminous and most cheap inverters require full voltage to charge a batteries correctly. Get a stabilizer if your voltage is low/unstable

Hello people.

Has anyone here used this cloud energy sunbox pro solar generator (pure sine wave inverter + AC charger + in-built battery).
It is advertized as having a pure sine wave inverter and 12V, 70AH lithium battery and sells for 160k on jumia.

I would like to hear about it's real life perfomance from anyone who has used it.

please is growatt hybrid?

Good morning house, I was recently faced with a challenge. I have a 24v 5.4kwh LiPO4 bank and a 600amp 24v used Ritar battery bank. Tested alone the LiPO4 did not meet my daily need. It will usually go off around 2-3am (when I personally need it most!) and the used batteries much earlier at around 12mn at times.
I was discussing this challenge with a friend and he told me he connected his LiPO4 and SMF bank together(in parallel) to the same busbar and that has resolved his problems.
So I checked online https://community.victronenergy.com/questions/19981/mixing-lead-acid-and-lithium.html and realized many others have tried it with the pro and cons, different charging and discharging profiles mainly.

So I connected 200amp of the Ritar to my lithium bank to test run. I also used 28.2v bulk and 27.4 float charging profile on my inverter and CC. All connected yesterday evening. I was able to use the system overnight and even ironed with it this morning, however I was aware there was grid supply at some points overnight and therefore I can't say if it works or not.

It is early days yet. The risks are shortening the lifespan of the lithium and undercharging the lead acid but based on what seems to be happening as described by others, due to the BMS, lithium charges and discharges first and the lead acid charges and discharges last.

I will update the house on my experimentations and hopefully, no big bang episode!

Growatt 24v hybrids I see can't take my current 8s1p PV voltage input.

I may have go SMK again or get a standalone 24V wall mount inverter and a separate CC.

Any suggestions house?

1. Remote monitoring

2. Configurable parameters

3. Lithium compatibility

4. 100V max. For 24V variants

5. Up to 1500W max. power, over sizing is allowed

6. Atheistic design

7. A medium range product for money.

In case you plan to get one, I can hook you up.

get a growatts and reconfigure your s to 4s2p

Easier if you have your connection reconfigured

Assuming you used 150W which has up to 23V as VoC

Choice is all yours to make.

Cheers

Just watch closely

What I meant was that the 600W PV you have will never charge your batteries full any day of the year

Except you have grid available for up to 18 hours cumulatively then it's no problem at all.
