Yes you can. But if ur choice of battery is a 12v Lead acid, don't do more than d c rating inside d batteries manual or on d body. If your going for lifepo4. Ur battery can safely go as high as 1c. But that doesn't mean you should load ur inverter pass 60-70% of it's actual capacity. U will break it in no time.

earthrealm:


its ok, but doesn't make sense...its like using a bike to move from lagos to abuja, vs using car
why do you think you need a 7.5kva inverter, the bigger the inverter the bigger its self consumption energy

Milito:


The inverter is just to backup lights and computers in a workplace until change over to gen and vice versa (less than 5mins at different times throughout the day only).

A number of the lights are halogen spotlights with high energy consumption; which was why the load Audit recommended 7.5KVA. The 4 unit battery is to save cost in view of the small backup time required.

Milito:


What is C rating please?

Any clue from the attached pic?

Is this type of charge controller suitable to charge a 5kw/24V lithium battery

brightk:
Btw jinko and Canadian panels which is better.. Apart from gennex, any reliable seller for original canadian panels

funshyboi:
Please is anyone familiar with this charger. It’s LiFePO4 battery charger. Who has the idea of where I can get it fixed in Lagos

Hello Good People,

My 5kva/48v inverter suffered lightning damage a few weeks ago. I’ve spent some reasonable amount of money in the course of the repair, and I wouldn’t want to have a similar experience again.

Please I need a help on how best I can protect the inverter from lightning damage. I would appreciate any device (with price) that can help me achieve this protection.

Thank you all in anticipation to your kind response.

This has been discussed extensively some pages back and on the DIY Nigeria Telegram group. A lot of times people forget or overlook the safety aspect of their installations forgetting that Sango, Thor & Amadioha belong to the same whats app group and start doing press up during the rainy season looking for who's inverter to smite. For any basic installation you are first and foremost expected to have a functional earth system installed in your house. You may be using an ELCB or RCCB depending on what was installed. Test it and ensure that it is functional by a qualified electrician. You may wish to also install a lightning arrestor to serve as an potential pathway for any strikes Thor might send your way. Finally for your system, you are expected to install Surge Protection Devices (SPD) at both the DC side from your charge controller and AC side input from the grid. This can significantly help your chances of recovery from an indirect strike. But ultimately there is nothing you can do to prevent any damage from a direct strike on your house. You can order directly online from AliExpress or from some of the retailers here advertising on the thread. Hope this helps a bit.

Thanks for your help.
Can you please send me the link to join the DIY Nigeria telegram group on 07035383828.

Secondly, will the ratings on the pictures you attached be perfect for protecting 5kva/48v inverters?

oloet:


I will advise that you buy a new one rather than repair because how sure are you that the charger is going to be optimal after repair

Loneley:
Hi guys, I'll appreciate your opinion on this.

Picture 1 shows my inverter's battery indicator with the battery full.

And picture 2 shows the battery when external power is cut off, it drops to almost half.

The installer would come check it out on Saturday, but before he does, I would like to have an idea of what's responsible.

The system was set-up about a week ago.

earthrealm:


the dropping to half, is it with load or no load?

but first off, those battery level indicators can be error prone. best you use a digital meter to test the voltage at the 2 different times. is the battery flooded type?

Lightning arrestor and surge protective devices are all u need

dollarnaira:


Is your inverter GSR?
Battery as Tubular?

Loneley:
Yeah, it is.

The battery is also GSR

dollarnaira:

Tubulars need the right amount of charging current and voltage ( the voltage especially).

Check the sticker on the battery for better information.

Loneley:
Will do when I get home, thanks.

Still, it doesn't matter how long it charges full from the panels or public power, like for example, last Sunday, there was light throughout.

Yet, once they took the light, battery indicator immediately dropped by almost half.

Get a Dc meter to check.
Or a voltmeter.

Are u on 12 or 24v system?

Greetings great minds
My inverter has been acting funny, works normal since i installed, I usually charge with panels alone for about a month till the devilish nepa reinstall the power grid, on the first day I charged with nepa light during the day, then at night when I started using with load less than 0.007% for 30 min it started giving signal for low battery, upon checking the inverter the bat voltage has dropped to 11.6 while the charge control was still on 12.2, if i off and on after some minutes the inverter comes back to 12.3 or above and the cycle continues..

This has been happening for 3 weeks now,

Someone pls come to my aid

Details
Inverter :new famicare 1.5kva
Battery : luminous 220am
Charge controller : powmr 60apms
300 watt x2

earthrealm:


YOUR battery is weak, either the electrolyte sg is wrong, or you inverter and charge controller isnt giving the battery the correct charging voltage. check that ur charge controller is configured to send 14.7volts to the battery. your inverter is a dumb inverter..so you cant change the charge voltage---.

how many amps or watts do you see on the charge controller at midday in bright sunlight?...or attach a picture of the charge controller screen if you dont know what am asking

Hollawayn05:


Thanks sir
The charge controller shows above 13amps and 200watt at peak period and how do I configure my cc to give 14.7V?
