I think you are probably referring to the felicity inverter, mine is the hybrid IVCM3024 it's rated 2.4kw but my MPP (of blessed memory) is 3kw with 6kw surge support and I have pushed both close to peak (at sunlight peak and nearly full battery).

ojeysky:
The felicity also has no Problem taking the rated capacity, I have pushed it over 2kw before and it's rated 2.4kw. Nevertheless the conversion efficiency is what catches my attention most. One will have to make a decision to either increase battery bank to cover for the loss or go for the xtm.

Let me turn to some MPP users, @earthrealm what's the efficiency of yours like?

earthrealm:
this inverter sweet o,
JUST THAT ITS EXPENSIVE
is it hybrid?..ie with inbuilt CC?

ojeysky:
How much do you sell the 3.5kw/24v?

Trippledots:
I think fan is DC ceiling fan, not standing fan.

@ juo can you recommend an efficient chest freezer with same or close power usage?

ojeysky:
Fan at 5 watt speed eh.....that one na hand fan o, and 3 watt bulb eh? Isorite. With the bolded na KIV o

ceaser:
A fridge that sustains at 30 watts. Please what is the model of the fridge, average volume and the product manufacturer?

ojeysky:
Interesting, though I think the bold may be an exaggeration, but I note that you are on 48v, normally efficiency is improved as you climb up the ladder, nevertheless I think your system efficiency is better. What kind/brand of inverter are you using? Will see if there will be a difference with MPP when it comes back alive.

ojeysky:
By AC on do you mean utility on or your air conditioner? I decided to power on my Air Conditioner just for check, difference was a little above 100w.

Now tell me, are you saying that you were solely on battery with a load of over 600w and the loss (and inverter consumption) was a total of 28w?

ojeysky:
Through my BMV and cross checked with my clamp meter as well. Figure in red is from BMV while the white(AC out) is from inverter, the difference is the consumption of the inverter plus, BMV consumption plus Q factor which is minimal.

Which model is that? cos am using felicity as well (though 24v) and it's less than 50w

Idle or under load? My Victron VE.Direct 48V is 12W too, under heavy loads (tare of 9W)

Janyves:
Oga Niyi, you're right. With my little experience with xformer based inverters, I'm yet to see any idle power below 14W(12v) , 21W(24v), 28w(48v). But I've seen hungry one's ∼48W(12v), 108W(24v) ,192W(48v).

Pls whats the mileage

dejidotun2000:
What is the criteria for enrollment in that class ?

earthrealm:
a veli veli good kwesion , something wey you tell me say na 65k some time ago.......i pick race
i need 2 units now now, sharperly

This is the unit am talking about

earthrealm:
Hahahahahahahah.
Are you sure JUo sells it for 40k

mcTrinity:
Chai.... Even those that, in the past, mathematically and analytically proved, beyond reasonable doubt, that LeadAcid Battery is preferable HAS now gone Lithium.

Oh father, in this 2020, deliver us from all motivational speakers... It is well oooo

ceaser:
Heh, someone should import it nau. Guys will buy it and test it out and relay the UX back for peeps.

I can invest some amount into the testing, so long as the importers will not sell it at cutthroat prices. You know Nigerians are opportunists hiking prices at whim.

earthrealm:
thanks gents for the suggestions.
seems the dc pump is a better option. am wondering if anyone is running such, lemme tap from his experience.
2ndly is the pump easily available in nigeria? or aliexpress..hence the need to purchase 2 pumps, incase of 1 going bad

3rdly, can i hook it up directly to the solar panel, without battery?

4thly, if answer to 3 is yes, i am considering retaining the old inverter setup, however the output from the panels will be split into 2, one going to sumo...the other going to the CC of the existing setup

i wish to automate the whole system, with auto flow shut off, so the system will be independent of human input, as setup is in the village. a regulator will be installed in the tank to cut off power...when tank is full...and also activate power when the water gets to a certain level.

the water demand is minimal, say 200 liters daily, so a 2k liters tank shud last 1wk or so. borehole depth is btw 80ft to 130ft. most pumps are rated flow/hr like 2000ltrs/hr...or 30L/minute , can i simply divide by 24hrs to calc the hourly flow rate....abi the pump is designed to work 24/7??

earthrealm:
ok, u can use a clamp meter to check if battery is charging?
2ndly, even though its new, the battery may hv sulphated /damaged while in the sellers shop. so you may consider buying a new battery, if you confirm ups is charging

earthrealm:
am looking for a budget install for borehole water supply.1k or 2k liters tank
am looking at 3 options. has anyone deployed any of the options listed , or has a superior option to recommend to me.

note: 2 x 250w panel , 850va luminous hybrid inverter, 12v 200ah quanta battery, 12/24v 100voc fangpusun 50aD mppt CC already exists in the house

option 1: get a dc sumo pump and power it directly from solar panels fitted with overflow regulator

option 2: get a normal 0.75hp or 0.5hp sumo pump, get 2 x 12v 200ah batts or equivalent LIPO4 and 4 to 6 units of 250w panels, with a 2kva or 2.4kva hybrid inverter with surge capability

option 3: get a battreyless inverter and connect the sumo in option 2 directly. 6 x 250w panels needed

ceaser:
Please at what prices bro?
