Location?
Is the inverter coming up but can't detect the battery voltage?

Or

It's not coming up at all

kristien4:
Location is benin city. It does not come up at all wen connected to battery. It only comes up wen connected to solar pv/ nepa light. Works via this too sources but does not detect battery. Everyother thing works fine. Displays/blinks "Bp" on the inverter screen. Its an ipower max 3.5kva inverter.

TechGeek777:


Bp means no battery present.

Does the battery have BMS?

Hybrid inverter?

Obnoxious2001:


Is the manual available?
What does bp mean

kristien4:
I've gone thru the manual. No mention of "bp".

Drgreatone:

Av u tried disconnecting and then reconnecting the battery? If this doesnt work, then likely inverter battery point is damaged and wud need repairs. Most inverters usually av a reverse polarity protection which sud av kicked in with urs.

Obnoxious2001:


It can be fixed.
Are you close to mm-way?

kristien4:
Yes..mmway is closeby

Trippledots:


E de bro. Like last week sef.

kristien4:
Tried it, didnt work

kristien4:
its normal tubular battery..

Your inverter no get overload protection? Which inverter be that

Abbeyb1ack:
My inverter just shut down due to overload...any engineer within sango axis?

jonescosmos:


First disconnect the battery and read the battery voltage across the battery terminals.
If you get the reading, see if it meets minimum startup voltage for your Inverter.
If yes, Battery is OK. If no reading or reading extremely lower than nominal voltage, battery is gone. If you have multiple batteries, try to read them individually.
If all the batteries checks out, open up your inverter and see if it has an inbuilt fuse, or any other blown components, sniff around the inverter mainboard and feel strange smell from, if yes, confirm that the fuse is OK or blown out.
If the fuse is blown replace it and try your connection again.

Abbeyb1ack:


So I finally disconnect my inverter and took it out for repair.....(nt knowing dere are steps and precautions)


I reconnect the inverter back but my charge controller no ON

I called my installer....he said he will get back to me

I just hope I neva spoil another tin

isangjohnson:

If it was just the overload that shutdown it down, everything including the charge controller should turn on when you remove the loads.

isangjohnson:

If the seller doesn't open up to me on why he's selling 12v 200ah/220ah LA battery at that price, I would be scared.
There are a lot of used batteries and other appliances in the markets that are well polished and packaged to look like new.
At this critical time, buying products from a known/reliable source that's willing to take full responsibility of the products throughout the warranty periods is what we need.

Good morning house.. Sorry to bother you guys.. I noticed these ports on my inverter and got me curious what's it's used for.. There also one like this on the charge controller..

RS232 and BMS/RS485

Thanks

swagifted:
oh yes, there office is before Vodi Tailors in wuse 2.

Abbeyb1ack:


Shld i say overload or plugging something too heavy into the system


But the issue now is I disconnected the battery and other wire connected to the battery nd took the inverter for repair

After repairing
I connected all the wires back to the battery
But my charge controller didn't ON only inverter working

My sachet inverter when pulling about 600va AC load, draws about 1kva DC power. That's about 60% conversion efficiency. Ambient temps was in the high 30°s though.

Has anybody actually measured their DC to AC conversion efficiency? I'ld like to know what they got. 🤔

Good morning, I want to get batteries for a 2.5kva or 1.5kva hybrid inverter. I just noticed that two 220ah batteries give a total of 440ah at 594k while four 150ah batteries gives a total of 600ah at 580k. By my local man logic, the 150ah option seems better to me cus I get about 160ah more battery capacity. Pls, those who are experts, is this my logic correct and can I go for this 150ah option?
