Thank you for being gracious in victory grin grin grin

Here below my prior efforts in this area - I will post more links as I find them. If you read these posts and the related engagements around them, you should pretty much come up with a full picture.

Please do not use the 'control reset' feature - rather first disconnect PV, make your updates then power cycle the CC (disconnect battery and reconnect) for a full restart (needed for custom settings to take effect)

First 2 links are about firmware updates, 3rd link is general info on pushing custom settings, 4th link is a caveat on a possible dangerous software feature.

Daly BMS is a good BMS brand and affordable. Another two brands you can check out also is Jiabaida & Jikon BMS both on AliExpress. They come with active balancers and are in use by many DIY enthusiasts on this thread. I however prefer the Jiabaida (JBD) for its use by multiple OEMS like OverKill BMS https://overkillsolar.com/ who customize it further and update the software.

After in depth research, I've gone for the JBD. I realise I could just ask the JBD CS on aliexpress questions I might have bothering the bms installation. smiley

Which do you recommend in place of lead acid battery? Is this same as wet cell battery?

Honestly, most this things confuse me. Got a company that gave quote of 1.1m for the 2.5KVA. Maybe I go with that.


SYSTEM SPECIFICATIONS

*2.5KVA INVERTER

*12V,220AH battery(x2) ...... wet cell battery

*1400W of Solar Panel Capacity ....Monocrystalline

*Charge Controllers......MPPT

*Installation and Set-Up inclusive



Jefferyzz:
Don't waste 420k on 2 lead acid battery o.. buying inverter n CC separately is even cheaper. That 3kva dey told you is 2,400w continuous running.

They are all lead acid... Its better u buy all your material yourself and call dem to come and Install.. none of them will give you lithium phosphate batteries quotation for 1.1m meanwhile you can have it all setup for that range. Buy your own material. If you're in Lagos. I can give you contact of where you will buy all except lifepo4 battery.. u can get those from valto.

Are you talking about a Parallel Setup? If yes Inverters must corm to same config and rules of Parallel Connection must be obeyed.

Some Inverters can be paralleled from 2 units till 12 Units and they must be connected to the same Battery Bank, Same Input and Output for Single Phase, and 3 Phase rules must be followed where applicable.

The basis of my question is that I have a hybrid inverter and I have come to learn that I can connect an MPPT CC directly to the batteries that the hybrid inverter is connected to.

What I wanted to know is if it is also possible to connect two independent hybrid inverters to the same battery bank.

Note that I am not connecting the inverters to each other in the sense of stacking them like some manufacturers allow to increase capacity.

I mean by that the loads connected to let's say both inverters are totally unrelated and unconnected.

Is this done? Or can this be done?

Simple answer Yes, as long as they are the same nominal voltage. You connect in parallel which means you just connect each inverter as you would have connected it if the other one does not exist.
I almost always connect my system with redundant parts because i travel a lot and if there is an issue ,it will be easy to direct Madam on phone without allowing anyone to tinker with my system in my absence.

As you know,if you use both simultaneously you will drain your battery faster is all. If both charge simultaneously too, note not to exceed what the battery can take.
Make sure You can isolate/disconnect the PVs of each hybrid inverter or CC if there is need for it .
Continue flexing you setup.

Thank you very much.

The other question on my mind is I have the Homaya 1.5KVA which uses 2 batteries and is a 24-volt system.

What would happen if I connected more than 2 batteries provided that I still maintained the 24 volt system (in other words, increased the capacity beyond 2 batteries but kept everything else the same)
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:35am On Nov 07, 2022
Interesting use of specialist DSE equipment.

One could have used an AC timer switch driving a relay for the Gen scheduled autostart (save money on a new Gen module) and used any of the available el cheapo chargers like Souer or even a PWM CC attached to a small solar panel to maintain the Gen starter battery.

For the Victron fans, the GX devices come with a Generator Start/Stop function that can do a lot of magic including scheduled exercise hours e.g Run 7am every saturday if the Gen did not run up to 4 hours in the week before.


jonescosmo:


Thanks Bros.
For your Gen, the same thing was happening to mine until I Changed the Control Panel and rewired the Gen with a DSE7320 MKII
https://www.deepseaelectronics.com/genset/auto-mains-utility-failure-control-modules/dse7320-mkii
and a DSE9130 12 volt 5 amp Compact Battery Charger
https://www.deepseaelectronics.com/power/12-volt-battery-chargers/dse9130

I programmed and scheduled the Gen to run itself without giving output for 15 Minutes every Sunday 8am. While the function of the Battery Charger is to keep the Gen Battery alive using AC supply from my domestic connection.

About what you read of Tubular Batteries, yes they evaporate into the air within the installation corner and should not be inhaled. If you have money, go for Lithium but be sure you respect Lithium principles because the can be very dangerous too if wrongly deployed or configured.

Inverters that are Wall mountable will be on the and those that are table top are kept on top of a table-like rack mostly on top of the Battery rack to keep things close and compact.

You can always see professional advice here if you run into glitches with your DIY projects.

Cheers.

Thank you boss. This Jiabaida (JBD) BMS looks complex (but interesting) to me compared to Daly. What's really confusing is the number of wires that came with it. The Daly for example came with the right amount of cable mouth (8s = 8 pieces of cable to attach to the battery) which seems pretty straightforward. I am expecting a 24v battery setup which will use a BMS 8s, where will the rest of the wires go assuming I'm using a JDB BMS? I have attached a screenshot of the wire that I'm referring to.

Additionally, does the balancer that comes with the JBD means I won't need to worry about my Cells not having a balanced charge out of the box, meaning that once I use JBD bms, it will balance them automatically, and I won't have to worry about looking to balance the cells before setting them up?

Kindly enlighten me on these... Thanks!

Edited: Also boss, from the little research I've carried out, I want to ask if it's necessary to top balance the lifepo4 cells when you buy them from 3.2v to let's say 3.5-3.6v?
Would the output performance became worse overtime if I didn't?

Because I noticed that to top balance a battery, you need a power source that needs to run for hours (if not days depending on the cell capacity you have), set to a certain amps, and I noticed that this needs to be done by someone that knows what they are doing in order not to fry the battery by overcharging them.

Some videos I watched even claimed that the active top balancer that comes with bms is not entirely reliable...

@ojesky
@valto
Kindly help share your thoughts on this.

Thanks

The JiaBaida BMS has an 8S version. If you are in doubt about the version you need, you can message the seller directly to guide you on the specific model that you need to select before making payment. The active balance function is meant to keep your cells balanced and spreads the cells voltage from high voltage cells to low voltage cells. This function occurs over a period of days as you actively cycle your cells. This is not the same as top balancing new cells before connecting them to a BMS and starting to use it.

Top balancing a cell depends on a lot of variables chief among them being that the internal resistance of your batteries are closely matched as possible. Another is that your cells pull the full capacity of their name plate 280ah should pull 280ah or higher not 220ah. To be sincere with you, most of the people i know and even i will recommend taking the time and top balancing your cells well with an external charger before commissioning them. Even with Lead Acid batteries. This is because the cells arrive at a lower state of charge (30%) and charging them to full saves you a lot of headache in the future. You can go ahead and couple the cells together and charge them with the BMS with the expectation that the active balancer will smoothen things over time but why take the risk of a runaway cell voltage bringing your system down.

There is no problem. That is connecting your batteries in parallel. This increases the ameperage of the batteries and not the voltage.

Your current 24v system is two 12v 200ah batteries connected in series. This increase the voltage to 24v but keeps the amperage at 200ah.

You just need another set of two 12v 200ah batteries connected in series making 24v 200ah then connected to your current setup in parallel to increase your amperage from 24v 200ah to 24v 400ah. However, you will need to make sure that your batteries are of the same brand and make. Also, its not advisable to mix new and old batteries as the old one will be pulling the new one down. Also, you will need to ensure your wiring is redone at same length for each connection. See the attached wiring diagram. Substitute the 6v for 12v in the picture.

oh really what do u mean I can't get real capacity

He means that the 15kwh LifeP04 battery capacity written on the nameplate is not accurate looking at the price listed at N1.6M. "Some" battery brands mislead their customers by stating a higher capacity than what their product can deliver in real life testing. Same thing goes for your solar panels too. Most of these substandard cheap Chinese solar panels do not deliver the rated nameplate capacity written on them (some have fake plastic stickers written on them). That's why you are usually advised to test the panels and buy named brands like Yingli, Canadian Solar, Jinko, Era, Trina etc.

Is there an MPPT that can charge the two sets of batteries at the same time?

I would appreciate recommendations from the house.

How many solar panels would go with the MPPT?

Thanks in advance.
