If you are able, please post a picture with the battery terminals clearly showing then I would be able to give any additional perspective.

So i finally got around to getting a pic of the quanta battery terminals.

2 more Panels added to make 2kw, with 4 new 150Ah batteries, now I can say I am utilising my GK series inverter. Generating over 1kw in the morning.

Quick question though, what would be idle float and bulk voltage for attached battery spec? I currently have 27.2 and 28.4 respectively, is that sufficient or should I up it further?

Unless you know how to communicate with the inbuilt BMS avoid it. They were sold out when I looked

They have them back in stock. And about the in-built BMS, it can be easily bypassed to use something like this:

I don't work for battery hookup but I like that they have really nice deals for DIYers.

Cost pls or is it free training?

looking for a cost and energy friendly ceiling or standing fan, it could be rechargeable as well, less than 30watts

Buy Qasa dc fans on Jumia. There is a 10w fan for 10,500 or you buy the Qasa Yoga fan.

You are on point Boss. In fact, I did some more research after you mentioned that and 2v Battery systems are recommended for large setups.

But I simply want to keep my setup simple, just 4 200Ah batteries. I will share some images as well so you can help me decide.

I am still undecided about 24v or 48v inverter choice as idle power consumption was mentioned earlier for the 48volts.

Please which of the series diagram is the best for running 4 batteries in Series.

Thanks so much.

I never got an answer. Please your recommendation and advice is needed

You will use a $17 bms with really thin balancing wires on a battery that size? And you will bypass the internal BMS how? Please explain. I am curious to know how you intend to accomplish that. I have a bunch of $17 bms in my office that I will give you for free after you purchase the battery.

I don’t think I trust that brand. Just a personal thing though

The qasa 10w fan you suggested to him is really cool. Have been taking full advantage of it's 10watt output for both my solar setup & prepaid meter. Got it on jumia for 10k & very easy to couple.

confirm it ships with ac to dc adapter/powerpack,
could u upload a pic of the rating of this powerpack, and the port/hole where its plugged in.
it doesnt hv an inbuilt battery abi?....and no space to install such?

comes with 12V adapter. it's actually about 30W.

Guys, what do you think about this 12v charger, any good? The plan is to use it with a battery bank of 2 x 12v180aH

Penuelseun:
hope it is not the black inec battery?

No. This is a DIY stuff. It has a BMS and lithium SCC purchased online.

chris81964:

How d'you mean by this please?

Plan to get a 120ah 12v li-po to replace 12v 100amp AGM battery that powers a 114 watts deep freezer. The startup power draw of that freezer nears 700 watts.

I really hope that lithium BMS will be able to handle it.

ceaser:


So guys, talking of timers, can something of a sinotimer be connected between the battery and the inverter for some form of automation? I wonder if it will not amount to inverter damage if the timer effectively repeatedly connects and disconnects battery supply to the battery terminals of the inverter rather than the factory way of using the switch of the inverter, bearing in mind the fact that the AC load is already primed/switched on to start in all these scenarios.

Thank you.

So in the prolonged absence of answers to the question I posted on here, I decided to take the plung anyways and experiment. And it has been a good performance for two weeks now.

The sinometer took a long time coming (ordered on AliExpress and yet to arrive) and running outta patience, I DIYed some simple automation to control the freezer one-off cycle depending on the SoC of the battery (100ah 12v AGM) hooked to a 1200 watts continuous PSW inverter, 600 watts solar panel 32amp breaker between panel and SCC and 30amp PWM SCC.

Toying around with some PWM SCC I have lying around, I discovered that the parameters are user optional. So I used it to replace the non-user option one that had hitherto handled the freezer.

I opened up the inverter and measured the switch terminal voltage to be around 13.2v, great. Then I soldered wires to the two terminals of the switch and ran it outside the inverter case and closed back the inverter.

I salvaged a 12v relay from a burnt TV surge protector, the relay has 5 terminals (2 for the solenoids and 3 for the NO (normally open) and NC (normally close) terminals on the relay. I identified the NO and the NC terminals and decided to go with the NO instead. This implies that the NO works (and therefore consumes battery energy - 50mA at 12v) only when the relay is energised which always coincides with daytime when the battery is charging.

I connected wires to the DC control terminals of the SCC and put DC out settings at 24hrs output, Low voltage disconnect at 11.9v, High voltage reconnect at 14.1v and panel off voltage (boost charging voltage) at 14.2v. This ensures that the battery always gets to 14.1v full charge everyday (usually by 9am in this sunny period) before the inverter switches on.

The wires from the DC control terminals are connected directly to the terminals of the relay solenoid while the two wires that run from the NO terminals connect to the terminals of the inverter switch. If peradventure the generator is switched on even before the solar panels start to have any appreciable insolation, the external charger connected to the battery charges the battery and the moment the battery voltage on the SCC reaches 14.1v, the inverter switches on.

By evening by the time the battery voltage drops to 11.9v, the inverter switches off till when the external charger comes on or till the next morning.

I tried a low voltage cut off of 12.2v but I discovered that the voltage of the battery drops to 12.0 when the freezer switches on, a voltage at which the inverter is supposed to switch off. Still thinking of designing some sort of few seconds delay circuitry to span the time the battery voltage recovers to above 12.2v before the freezer picks up, so I can increase the low voltage cut off to around 12.2v.

This is to serve as guide for those with similar challenges in simple automation.

Now I don't have to worry about the battery dying from over discharge. Life's good.

Quick question. Can a 600 watts 12 volt solar panel system be converted into a 24 volts or do i need to buy 24 volts panels again?

ojeysky:
2 more Panels added to make 2kw, with 4 new 150Ah batteries, now I can say I am utilising my GK series inverter. Generating over 1kw in the morning.

Quick question though, what would be idle float and bulk voltage for attached battery spec? I currently have 27.2 and 28.4 respectively, is that sufficient or should I up it further?

Please am still hoping someone will advice me on this. I really need to know if 28.2 is appropriate for bulk or whether I should adjust to about 28.8 since that is the info on the battery says but I like to hear from experienced folks here. Do you guys run your battery at such a high bulk level?

olatade:

I assume your 12v panels are 150watts each meaning you likely have 4 of it. Simply connect the 12v panels in series to make 24volts and then in parallel to make a 2s2p configuration. You end up having 24v 300 watts setup rather than the 12v 600 watts you had before.
