I have a prag 2.5kva inverter and 2 150ah Ritar batteries connected in series, but I've noticed a large gap in voltage on both batteries. When fully charged but with grid power on, one reads 14.22v while the other reads 13.45v.

When load is put on it there's almost a 3v difference as I've noticed one go below 10v while the other is still on 12.45v.

I have a 24v balancer hooked up to the system and both batteries are brand new, same batch and production dates.

What could be responsible, cos I've never since this before, but when separated each battery charges to 14.5v and maintains a relatively good voltage but when put together the wahala starts......

Good day all,

Please I am trying to upgrade to Solar system. I currently have a 1.5kva transformer inverter (see pix below), and was told I will need Charger controller, solar panels etc.

I also came across Luminous solar inverter (picture attached). So, I want to know if I should just buy this solar inverter or buy charger controller for my current transformer inverter. Which is better option irrespective of cost implication please.

PS: Batteries are Luminous 200AH 12V

Abdomox:


Yes, they are same make (Luminous), and bought same date at Simba in Surulere, 10 months ago.

Production date is not written on them though.

Holmes07:

If it's still under warranty, get it back to simba.

Holmes07:

Bro get a charge controller, the charging capacity allotted to those inverter for solar modules isn't so big.
You can contact me to get the installation done for you.

Abdomox:


You mean the charger controller sends more solar modules than the Luminous Solar Inverter system? Please help clarify.

how much for the 380w panel and the felicity lithum batteries (24 and 48 volts)

Dkev:


Can it be connected in series(for 24v) or is there a 24v version? There seems to be a tiny lcd screen on the battery, what does that display?

justcallmenuel:

The 380w prime solar panel is 47k each and the 200Ah 24v felicity lithium battery is 380k, while the 48v is 700k.

Sorry for the late response boss!

mctfopt:


The one that goes below 10v is bad. I guess even in same batch some cell of a battery may fail before the other does.

earthrealm:


What charging voltage is your inverter outputting to the battery. Does it correspond to the manufacturers spec??.. this is the Achilles heel of most small inverter battery failures

Was the balancer put from the start, what kind of load in watts do you hv on the inverter

saint2ace:


Bulk charge at 14.5 - 14.7 and float at 13.8, and yes it does correspond to manufacturers specs of btw 14.5 - 15v bulk and 13.8v float.

I've always had the balancer, so was put on from day one, also had a powerpulse desulphator hooked up but later removed it.

Batteries are about a month old.

earthrealm:


Looks good.. you omitted the minor issue of load .
Whats your total max instantenous load in watts, or list the items if you don't know.
I once ruined a batt bank yrs back, cos of this often neglected issue

saint2ace:


Load of about 200w, a 55" TV on eco mode max 30w, a laptop max 60w, 2 DC fans max 50w and 4 energy efficient bulbs @10w each 40w max. Then phone chargers etc

kiekie1:
Fairly used 200ah fullriver battery at 50k....Limited stock!

Bonus for prospects with miniature load demand: Mpower & Mercury 200ah battery at 30k ... Lasts approximately 6-8 hours on a 100w load

Condition: performing great . Interested buyers can carry out their brief test

Location: Abule-egba , Lagos but can be waybilled to any state as usual under buyers expense !


Feel free to contact me backstage asap if keenly interested as usual

One day like that Ogas Niyi & Ojeysky were discussing here & should I say they were speaking in tongues. Cos strange words were being spilled everywhere.

Tasmota
Node Red
MQTT
Flash
Sonoff
Emoncms
etc

Had to roll off my YouTube bundle & went searching. Surprised that instead of seeing Solar monitoring what they were teaching was home automation. Looked cool and all that as you can incorporate solar monitoring into it and many other things.

Annoyingly, no one ever stated a starting point. Like acquire this, this and that before you start DIY & programing. And these are where to buy them from. I don't know if anyone here can help me with that.

Just tell me what to buy and where to get them to get started. Raspberry, laptop, arduino, sensors, softwares to get.....these things still look & sound like imaginary substances to me. Thanks.

Good day,

Please I need Fangpusun VE. Direct to USB cable. Any vendor who has it in stock should please leave his contact.

Thank you.
