Typically a good 3.5kva inverter should be able to accommodate 2x surge, if that is not the case then that inverter isn't good enough. I am also not sure a 1.5hp pump surge should get up to 5kw....I have a feeling yours probably tripped because of battery lvd

Imagine pull 3kw from a Lead Acid, Lol that's 125Amp at 24V just expect LVD.

Okay. Lets hope someone else comes up with some practical report.

I used my 3kw GK series MPP hybrid inverter to power my 1hp pump comfortably with all other loads powered on, so am pretty sure 1.5hp won't die on it

I'm not sure u get wat d first guy is driving at
1. 3.5kva he's talking about is most likely 2.8kw in few cases it might b higher or lower than the above figure
2. 1.5hp is not 1hp
3. Ofcourse 1hp should do fine with 3kw inverter, as it requires around 1.2-1.5kw of energy.
It's best if e can go bigger. So as not to waste money

Please what size of charge controller will I need for 5 Felicity Solar Panels of 540watts.

Would it be safe to call this 2.7Kw system?

Can anyone recommend a good quality and cheap charge controller?

Also, I don't see people speak much about performance of LifePo4 batteries, any testimonies of any specific brand?

I see people using an extra circuit breaker as part of the installation setup, what part of the setup will this be?

Powmr mppt sold for 61k here. If that is cheap enough for ur budget.

Whats the ratings, and where is location you are speaking about

Has anyone used era solar panels here, if yes what are their performance and comparaison with other tier 1 panels..

Jefferyzz:
It couldn't b yes if
1. If ur battery is lifepo4 of 3kwh up
2. If ur panel is 4kw up n u can pump wen the sun is up, even wen d sun goes down ur panel should still generate up to 1.6-2kw while the remaining 700/300w will taken from ur lead acid batteries.
And most importantly, ur 3.5kva inverter must b those variant with toroidal transformer, they handle surge better, if ure using a high frequency inverter, don't pump

Hello bro,

1. How is your "Crown Ricco" inverter doing, has it develop any fault since 9 months you have been using it?

2. Would you still recommend it?

3. Can one use it to set the battery to charge from NEPA only or from Solar only?

4. Do you know how much 5kva 48v would cost for Crown Ricco?

I get the point but I don't get why you believe a 3.5kw will be 2.8kw in practice especially if it's just to handle short load. I know axpert variants users here who have put over 90% load on their inverter without any issues and when I used axpert I had similar experience.

In the case of my 1hp apart from the starting surge it consumes less than 1kw. A 1.5hp outside the surge(which should not be more than 2.5kw) should consume 1.5kw or less. Note that the guy is asking about a 3.5kw inverter not 3kw... ofcourse if he has money he should feel free to get even 8kw

my sentiments too, *2 surge would be in the neighbourhood of 7kva for the short burst

I'm still looking for a way to talk to my 7.5KVA Felicity LF Inverter IVPS7548. Since I bought it, we never talked, we have just been looking and touching which is quiet unusual for my equipment. I need to be able to hear what it is saying without having to go to where it is hanged, I have found some indirect ways of monitoring it, but I still long to be able to communicate with it directly.

Any help is welcome.

Still working 5n. There is a little defect in the design which I worked something to it. The fan doesn't come on unless the load on it is up to 50%. Iron will b running on it for 30mins n fan won't come on. I bought bigger fan n fixed it on the other side with a switch, so I put it on b4 I put on my iron.

Absolutely, its always on even wen I'm not at home, with freezer on it. I can count d number of times I put it off.

Ac charging parameters are adjustable, it's not an hybrid inverter, d only charging option is AC, charge controller handles the solar charging.

I no of 3.5kva 24v, don't know if there is a 48v variant.

3.5kv is same as 2.8kw in most inverter u will see out there in d market
Kw=kva*pf
Pf of 0.8
I thought the op mentioned 3.5kva n not 3.5kw

I used to use my 2.4kva homaya to pump water during the day when the sun is up. Not sure now about the power rating of the pump but it was a surface pump.

Irrespective of the amount of battery you have, a 1.5hp submersible pump will shut down your 3.5Kva inverter. I dare anyone to try this and report back to the house. I have tried with a 3KW HF inverter before and it promptly shuts down. The pump initial power surge can get to almost 5kW. A good transformer (LF) based inverter may try, but I will like to see a report.

Was the defect on the inverter before you purchased it?
The bigger fan you bought is it serving as a cooking device to the inverter?

If NEPA and Solar are both available at same time, is there a way to isolate NEPA and charge with Solar ONLY (either by means of breaker/change over)?

Can you confirm the 5kva 48v from your source?

It's the way the inverter is. I added the extra fan cause the body get warm but d inverter fan will not start up until there's 50% or more load on it. If this should continue. It won't last long before parts start failing.
Fan should b controlled by temperature not by certain percentage of load

AC input has switch(MCB), u can always put it on n off

I'll ask

If it's an axpert variant perhaps you may be lucky to put off some data from it using the solpiplog, have you tried that yet?

It depends on the make of the pumping machine. My 1.5hp submersible consumes around 2.2kw steady though that is not a problem for my 5kva inverter but I won't try it in 3.5kva

Na wa o folks are really very conservative sha unless I will be pumping for several hours in a day will this be a concern. However I guess I should add that it all depends on the type of inverter procured. He should get an inverter with specification of 3.5kw and not 3.5kva... That's what I will get sha if I was in his shoes.

You can't use 1 unit of 220ah battery on a 2.5kva 24v system. It must be at least 2units of batteries.

Can i use 2 150ah tabular battery for the 2.5kva 24v inverter. Thanks

Any good reviews about era solar panels..

Good morning house. Pls how good is star plus tubular battery

How would anyone know. It's a new product buy and try. Well I currently use them and I'm hoping to get the best out of them.

There isn't any information abt the charging profile on the battery or the carton, no C ratings either. Though it is 220ah @ C/20. It Comes with 18months warranty.

You can go through their website

Sure, go ahead

Improperly sized cables to your submersible pump will amplify the surge from the pump. Another point to note is, if there is corrosion between the point where a cable was joined to the cable that came with pump, this will also amplify the surge. Part of the surge we see in our submersible pumps are coming from the points I mentioned & others I don't even know.

What I did, oversize the cable leading to my submersible pump & you will see a reduced surge. This will also help reduce power losses on the cable, meaning your pump will consume less kwh.

I once bought a 1.5hp submersible pump & was shocked how small the cable that came with it is. I had to cut part of it away & connected 4 mm2 Commester cable.
