I need a used 1kva or 1.5kva inverter if you have for sale kindly quote me.. must be 12v

emmy9500:
Hi, please will a 5kva/48v inverter carry 2hp air conditioner, pumping machine, freezer, pressing iron

Not all at the same time

olopan:
Okay!

There is a link on my bio (can't post it bcoz of spam bot), use it via your PC and input the loads as they will be used in reality.

* Share the screenshot of the final results

* Share installation location information with respect to the building

* Share a picture of the roof ( location on Google maps is not needed now due to privacy)

3nos x 1.5hp ACs
18w x 15nos LED Light fittings, 5nos laptops, 40w x 8nos security lighting, 250l deep freezer, water treatment plant, microwave, 8nos x 55w standing fans etc etc

2 storey building. Roof top measures around 10m x 12m

Hello house, I have a 5kva/24v felicity inverter, a 60A PowMr solar charge controller, two Vitra 12v220a tubular batteries and four 300W s. I noticed that using with from around 11am with my freezer, TV and two fans, the system goes off before 9pm even when I put off the freezer before 4pm. I expected to have at least 18hrs with this setup which is less than 3months old, but I'm disappointed with the results. I intend to add two more 300w s, please would this help increase how much supply time I get from this system? Any advise will be welcomed.

Tell us the power ratings of the gadgets you power. Whosoever advised you to power up a 5kva inverter with two 220ah battery needs flogging.

You can only power about 300watts (total wattage of the appliances) with those batteries as your inverter will use up about 80watts doing nothing.

My advice is you dispose those batteries and buy new ones atleast 4 batteries then double your s.

Ideally, you don't need more than a 1.7kva inverter. Plus don't you power bulbs, you need to factor in those things. In renewable energy, you energy supply is limited. Even common phone charger draws about 20watts.

Get a proper energy audit done for proper advice. Those appliances you listed up there may consume about 400w in total and it's alot of power to be drawn from 2 tubular batteries. You will have just about 4 to 5 hours back up after sun down

Yes, but u need to be sure that the s are arranged facing the proper direction n more so get the total cumulation of ur load to ascertain that the DC energy generated is sufficient for use during sunny hours n at night

Thanks for the heads up, i'll see to it and revert back so you can make adjustments

Load is over 600watts. How about if I get a 2000watts sachet inverter with the two extra s? I'm looking at optimizing the output with not much cost..

Well, that might help improve your performance. Your freezer and other appliances should only be used during the day, you will have to reduce your "sun-down" loads to a max of 200w. If you are lucky not to have damaged your batteries your inverter should go off around 1 - 2am.

In order to continuously power the load of over 600watts after sunlight till the next sun light you need a minimum of 10 220ah batteries. If you buy less than that be ready to replace your batteries in about 12 to 18 months.

So my advice, power the heavy loads during the day and manage your load once it's sundown. Your current battery back up can only a about 100w after sundown till the next sunlight.

10 x 220ah batteries to power 600W load for about 20hours?

Thank you so much for this insight. I'm so grateful.

Actually that's for 14 hours. Is it too little or too much

Something happened about an hour ago where I went to buy felicity inverter at Garki modern market, Abuja for those that are familiar with the place.

A man came to buy felicity lead acid battery 12v 200ah. He needed 2pcs for 24v system. He came with a battery tester exactly like the one shown below. The shop attendant brought two new batteries but after the test, one showed "good battery" while the second one showed "replace battery". The customer rejected the second battery and demanded a replacement which caused an exchange of words btw the shop and the customer as the shop owner refused replacing the second battery.

My question is has anyone here ever used this battery tester and how reliable is it

This battery Analyser is not accurate

Abeg Wu get connect of where I fit get sachet inverter.

@juror
Pls how do I get SRNE pwm cc?

no be small thing when i say most of the popular brand in Nigerian market are fake capacity and also used grade C cells, they will say i am a marketer and attack me. hope una de see am

This is felicity battery as well using old cells

Good evening, house.

So, for almost a year, I have been off the grid. But recently, I decided to connect back to the grid.

My installer made a connection between the power from the grid and my inverter. So, if they take the light, it automatically switches to the battery power.

Now, my dilemma is that I share a prepaid meter with four other (4) tenants. Would this connection not increase the electricity bill?

PS: My is enough to charge my battery, except for this period, I don't get enough sunlight due to their orientation on the roof. I will switch back to off-grid in the coming month.

It will increase it. That thing dey gulp prepaid like mad.
Once in a while I use PHCN to charge my battery too and I notice a significant drop in my remaining unit.
It also depends on your battery capacity sha.

Thanks for the response.

I will stick with manually using the changeover to switch between the inverter and PHCN. That way, my battery won't get charged with PHCN.

I have this tester, and I can confidently tell you it ain't reliable.

Pls who has sachet inverter and AC charger seller

Currently fighting with my Chinese battery supplier because he has only Grade B cells. So my people be buying Grade D cells in Naija

This video must have hit a sore spot. This is the fastest I have reached over 300 views in more than one year.
There is a lot of pain in our market. A lot of deception too.
Buyer beware.

IMO, Grade A cells aren't accessible to random end s.

Pardon me... you're rigth! Was thinking it was too much!

It's Ricco crown not growvolt boss. It's still working 5n o. I'm installing new system with lead acid n sachet inverter dey friendly with battery consumption. I think 5w

TechGeek777:


Boss, what happen to your Grovolt inverter?

Pls who is currently using a pwm cc for any lithium? I need the brand name of one urgently. Pls share!
