Good morning house
Please I need your assistance, someone want to change his inverter and want to import it from USA and needs it to power;
5x 2HP AC (from 7pm to 9am)
5x water heater (3 hours at most a day)
2x deep freezes (270w and 120w nameplate) 24/7
2x fridges (300w and 130w nameplate) 24/7
1x LED TV
1x sound system
(Max of 5hours/day)
Can 15kva power them all or should he go for 20kva. As he was previously using 10kva/48v inverter with it (with 24x 2v/1500Ah GasTon VRLA batteries) but got burnt.
|Re: Solar Energy, A Complement To FTA by Barezzi(m): 8:27am On Jun 22|
Go for 20kva.
All those loads ON at the same time, will draw over 13kw.
|Re: Solar Energy, A Complement To FTA by Feshizzy(m): 8:42am On Jun 22|
Do note that ac and fridge draw x3 for their rating on starting up though,
50kva would be good,
20kva would be overpowered by all these appliances

I always enjoy your youtube clips
but don't you think this one is coming a little late?
however, it is more elaborate than others I have watched
thumb up, sir!

All powered on at the same time or staged?
Secondly, I'd rather we talk in terms of kW that kVA. This power factor of a thing isn't consistent across manufacturers and can prove a terrible bottleneck during system design.
For the record, state the power rating of the water heaters.
Having said that, 15kW should be more than adequate (most electrical devices are not supposed to be run higher than 80% of their rating, for lomg life, smooth operation, leeway for variations and surges, mystified power ratings by nameplates and a plethora of other reasons but most of all, personal safety).

Thanks for the reply I will verify that and get back to the house
|Re: Solar Energy, A Complement To FTA by pranil(m): 3:30pm On Jun 22|
Your friend will benefit by changing the AC's to inverter Ac's - The LG; are 200 K for 1.5 ton and 160 K for 1 ton. The load is reduced by almost 60 % when in Gen/Savings mode. His batteries will also last longer - http://www.lg.com/africa/split-air-conditioners/lg-BS-Q096J3A2?
The peak starting load is shaved off as the load ramps up slowly
I am running 4 Ac's , washing machine dryer , 3 TV + Decoders other electronics +2 fridge distributed across 3 No. of 5 KVA inverters and they barely reach 60 % loading
|Re: Solar Energy, A Complement To FTA by Feshizzy(m): 3:34pm On Jun 22|
You the Boss,
He is just a user with limited experience on balancing the load! Or atleast that is what I assume,
They good just switch the inverter on,
And hurrily start flicking switches,
And again I don't believe inverter AC are in play here with the setup!
|Re: Solar Energy, A Complement To FTA by mcTrinity(m): 8:42pm On Jun 22|
50kva? bros, they're not planning to power a community...
I'll go with the 20kva as suggested by Barezzi, as long as the loads won't be allowed to come ON at the same time.
Switch on one AC, give 5-10secs before switching ON the next. or better yet a Time Delay On Energise (TDOE) relay (timer) can be incorporated to the surge loads
My little contribution!

in addition to the above post by pranil, your friend could further reduce his total load by installing a solar water heater.
for almost the same cost, he could replace those 5 electric water heaters with a 300 litre solar water heater which
would take care of his entire household hot water needs even in the rainy season.
you didn't state the model of water heater he intends to power with the inverter but if it is ariston 50l, that could be a
whopping 7500w (1500w for each water heater multiplied by 5) eliminated from his load calculation. that is a
lot of power savings, if you ask me.
|Re: Solar Energy, A Complement To FTA by DMerciful(m): 10:49pm On Jun 22|
Buy Nickel iron battery(iron edison) and forget about battery for 50years! Question is can your fund the cost?
|Re: Solar Energy, A Complement To FTA by Monlo: 1:43am On Jun 23|
Hello the merciful and generous scholar!Can we get updates on your recently acquired LiPO4 batteries?As far as I am concerned,long lasting batteries are the bedrock of Renewable energy!

efuro:Good morning Efuro. Thank you for enjoying the videos. They say that when a person wakes up is his morning. There are many videos on YouTube that deal with monitoring with the Combox. People have also done video on Victron color control. We plan on doing one very soon. We are not really reinventing the wheel. All we have done is show that you can do it in Nigeria as well.
|Re: Solar Energy, A Complement To FTA by pranil(m): 6:21pm On Jun 23|
The plumbing and piping is the main deterrent for going solar on water heating not the technology . I am also dabbling the thought but have not taken the plunge .
|Re: Solar Energy, A Complement To FTA by pranil(m): 6:29pm On Jun 23|
Fit the Solatek, AVS before AC and set the timers on different time so the AC's come one by one on and not at the same time.
Also keep in mid the the conventional AC's compressor still cycles between on and OFf every 8 to 10 minutes while inverter AC's just reduces speed
For such a large load the user can also benefit from centrally cooled AC based on Heatpump such as this - http://www.robur.com/chillers/gas_absorption_chiller_ga_acf
Battery power is the most expensive form of electricity in the world ( the Ac's in this case run on battery)
|Re: Solar Energy, A Complement To FTA by DMerciful(m): 7:08pm On Jun 23|
My LiFeO4 is performing excellent. My confidence level on my batteries is solid....still counting time sha
|Re: Solar Energy, A Complement To FTA by Oshomo12(m): 8:39pm On Jun 23|
What is the spec of ur LiFePo4? That's the battery I am saving toward.
|Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 10:18pm On Jun 23|
the beauty of solar water heating is that it can be retrofitted to existing house plumbing - and that's what i did
in my case.
when you do the maths, the energy savings over 15 or more years of its lifespan far outweighs whatever
extra cost of plumbing that may be incurred in the short term during installation.

I am currently decking part of my duplex that is under construction so as to create a roof terrace. I'd like to situate a 300 liter heater like yours there and may engage your assistance when finishing. What are the installed dimensions of your system, stands included?
Thanks for showing us this much preferred central water-heater option.

Does anyone in the house has the midnite Wizbang Jr (MNWBjr) and the standard 50mv / 500A Shunt (MNSHUNT) for sale

|Re: Solar Energy, A Complement To FTA by SolnergyPower: 4:39pm On Jun 26|
Good day friends.
Do you have experience with FELICITY INVERTERS, how efficient are their inverters?
|Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 5:25pm On Jun 26|
the most important dimensions you should worry about is that of the frame which carries the tank.
i will climb to the top of the water tower and take actual measurements by weekend and revert.
|Re: Solar Energy, A Complement To FTA by efuro(m): 8:13pm On Jun 26|
My inverter waste much of my precious battery power.
It’s my belief that DC watt is 92% of AC watt and current stays same whether DC or AC.
Can someone help with explanation why my inverter draws so much juice just to produce so little. For instance, it draws 11.60A@307W DC to produce 1.47A@247W AC to power load (of a Deep Freezer, 32” LCD + 2 Decoders, Newclime Ceiling Fan).
See readings at 8.59AM this morning.
For the time being, I installed DC watt meter at output of my Battery Bank and another just before my CC to read-off harvest directly. While AC watt meter to monitor my AC loads.
An experienced explanation will do my nerves good.
(Meanwhile, my inverter idle state is just 27.7w and has good surge allowance when fridge and freezer compressor kicks.)
