earthrealm:


ok, i remember this your setup, tot the issue was thrashed then?...
i recall some pages back, you said you have 2 batteries?...and listed a bunch of loads, including freezer etc.
its a bit confusing going back forth. confirm its 1 battery you have or you plan to add another?.

it best you make a fresh post, list all your present/planned loads. confirm your battery nos etc.
its best you prepare and buy a new inverter, if u are planning to upgrade to 2 batteries, as that inverter is notorious for the charging section to fail, if subjected to big battery charging

I'm definitely not going to use this inverter
also I only have just this one batt3
I read on here sometimes ago, it's no good adding a new batt3 to an old setup as it could have negative effects. right?
so that's why am opting to buy new battery if possible the other type of batt3 (lead acid or so).

thanks again

Please Help me oh

Hi Blueprintz,

I believe earthrealm has done justice to your enquiry...
My little addition though is that you can get a DC Voltmeter for your battery. You can get 4 pcs, connect 1 for each of the batteries and then connect one to monitor the full battery bank. Then, you need to have a "Voltage against State of charge" chart. This chart helps you to know when you're running the battery down to a certain level.
If when you're about to sleep, you discover that your battery voltage is already down to, say, 60% (based on the chart), depending on the load, you can decide to shut down the Inverter so it doesn't drain within the night or you reduce load appropriately and ensure the loads left ON won't drain the battery during the night.

For the Balancer, I believe the HA02 model can still serve. Have 3 sets of the cable appropriately connected to the 3 batteries, while you safely insulate the last set. DON'T leave the last unused set exposed. I don't how long you've used your batteries, but Battery Balancers should be connected at the initial stage of the battery installation...

Cheers

I have 3 new batteries connected to my inverter and i read that gel/agm battery should not be less than 50% when using. How can i prevent the battery going below that, assuming am already sleeping. [b]Do you guys have any device to shut the inverter automatically when it get to 50%?

What I did in my own case are these:

• Ensured that the inverter switch is a throw switch kinda (like that type on tonididdy inverter), I avoided an inverter with the soft press switches.
• Soldered wires to the two terminals on the switch and ran the wire outside the inverter. These two wires if connected together will equally switch on the inverter since they are directly wired to the inverter switch. These wires form the terminals for my external switch.
• I secured a PWM charge controller, not to charge the batteries, but to serve as a low voltage disconnect device. I got a PWM CC that has user programmable settings (load on, load off values can be changed on the controller). These controllers usually have in built relay switches that does that job. This PWM CC will be powered as a LVD using voltage from the output terminal coming from the actual MPPT CC that charges the batteries. The wires run from the output (3rd pair) terminal from the MPPT CC to the battery input (Middle pair) terminals on the PWM CC.
• I DIYed a relay switch to be at a Normally Closed(NC) position. This switch has two input terminals which will connect to the "light control" terminals on the PWM CC and two output terminals that will connect to the two wires from the inverter switch. NB: I DIYed this when I got inpatient because of my LVD device order from AE was taking too long to arrive.
• The PWM CC Low voltage disconnect and high voltage reconnect was reprogrammed to the desired values.

How it works: The output terminals on MPPT CC reflect the battery voltage which is sent to the battery terminals of the PWM CC. At LVD, the light control (3rd terminal) of the PWM CC trips and switches off the relay which switches off the inverter via the wires that run from its switch. At HVR, the reverse happens. The inverter therefore automatically switches on and off a cording to the preset HVR and LVD respectively, a the while the actual factory switch on the inverter will be in the off position and useful only as manual override.

NB: I could have bypassed the use of a PWM CC and used the light control terminals on the MPPT CC to control the relay but I disappointedly discovered that the latter does not have an editable high voltage reconnect setting.

Disclaimer: The inverter tweak may void warrantee on the item.

hi earthrealm thanks for taking out time to quote me. I really appreciate.
I want to do a fresh setup.
the only thing will go to the new setup is my (3) 150w panel.


Shalom.

I want to know inverter, SC and battery details and possibly refer brands for me (pocket friendly durable brands pls).


the photo is my current setup.


I am willing to take you up on this, give you professional advice on what exactly you need to do to revamp your set up, and get a better setup with optimum performance, using durable and strong system design and devices.

I bought the 48v Felicity lithium and my first impression is not good. I tried to do a test drain overnight. It gave me about 90AH drain overnight. I then set my Water Pump on it to drain it further. I got to about 115AH when my inverter shutdown at about 49v. I wasn't sure which shut down first, my inverter or the battery. But the battery was still (or back) on when I checked. At this point, I can not recommend this battery based on expected AH output.

That's 5.8kwh at 49v would be at least 80% DoD already, what was it rated for? If 7kwh then it may not be a bad deal afterall

.

I bought this battery too but I have not really gotten time to do a compressive analysis of it.
But these are my few observations:

1.Battery didn't come with full charged, therefore, you have to fully charge it before use to determine the true capacity

2. Inbuilt BMS will not allow you drain it below 48.8V (90% DOD).

3. KWh test?... Loading...

he prolly used a copper/strip bus bar with several 50mm or higher cables. these are readily available.i cant remember his array size again, but he has listed it severally..together with his battery bank specs too. its a one off 5m to 10m naira project...and you go to sleep.

Put another fuse of similar rating and test, it cannot "blow" inasmuch as the fuse is within the inverter's rating

After a more detailed look, I can confidently say that this battery is 120AH or 5.7KWh. It is made of 16 prismatic cells of 120AH each. I think Felicity is guilty of false advertising and should be reported to Standard Organisation of Nigeria. It is neither 200AH or 7.5KWh.
