Please, can anybody help me review the Prag 2.5kva inverter or direct me to a link where i can get review or more info about the inverter. I found out that mine doesnt charge at certain input voltage, even as high as 157V and what is the importance of the 10A and 20A button behind the inverter with respect to charging current or voltage . Most times, i have to use a stabilizer before it charges..

2. the voltage reading and battery level on my CC is always different from the battery level on the Prag inverter. WHich reading should i trust most? Thanks
the input voltage on the inverter is 190v. If the voltage drops below 180v the inverter will automatically enter battery mode. The avr is a scam. The 10a will charge your battery slower than 20a. The display looks like disc light. Battery and load bar is something else, not accurate. Please use the inverter voltage reading

this is from my own experience you can share yours. Design is poor. Casing looks like stabilzer casing. Screen looks like disco light. Avr is a scam at 213v input and output are same. I loaded 400w watts load bar didn't move. At 25v battery bar still shows full. Switch over from Ac to dc is about 7ms too far for a ups. The charger is excellent. The only good thing in this inverter is charger that can charge to 29v. Please use the reading on charge controller to monitor your battery. @dunka you can share yours

Pls i want to install a solar inverter system in my home that can power 3tvs+2decoders, 1fridge or freezer , 3fans and 8 energy bulbs through the night say at least 12hrs.

What unit of inverter, batteries and solar panels will be sufficient for this set-up and cost+installation.

pardon me as i no understand all this calculations here.

Hello guys, I must commend every contributor here for a job well done. Bravo to those who freely share their knowledge and demystify these things. I need your help with this please:

Present status:

I have 2Nos of sukam 1400VA UPS inverters, also I have 2Nos of multipower 12v/200ah deep cycle batteries, the house is presently powered by 1 of these inverters connected to these two batteries. The inverter is charged by a TEC 5.5kva gen which is run for 4hrs a day, some times PHCN also shows face. The inverter is mostly used at night and this is the normal loads.

1. 3nos of standing fans ( at least I know one of them is 30w)
2. 8 nos of 15w energy savers ( puts all off when its sleep time)
3. one laptop + five phones

Thinking of Solar:

I like what I've read so far here, so if am to go solar, I will like to stop the use of gen, hence I will need to power the freezer (150w), and a 46" LED Samsung Tv. If it will help me, I can power the freezer for some hours and put it off.

Question:

What will be my best way of going about achieving the solar dream if I have a ceiling of #250K?

avr in inverters is not like the normal avr.. inverter is inverter and must be sensitive to low voltage and as result automatically switch to inverter mode by default. . If you need something better get a servo stab from Prag.
so nothing is wrong with the inverter in question.

Thanks in advance.

250k can get you epsolar 60a charge controller from kiekie @ 135k, the balance can get 2 250W solar panel plus installation. You can add more solar panel with time to extend it to 1600W if your inverter is 24V system, or 3200W if 48V or 800W if 12V. With this initial setup, you should be able to generate between 1kWh to 3kWh depending on your location and weather.

Re: Solar Energy, A Complement To FTA by RipVanWink: 8:49pm On Jun 05, 2016
@pchinak, another option may be to sell off ur old inverter, then buy an axpert or ipowerplus inverter with built in charge controller.
5kva 48v comes with 60amp cc, 3kva 24v comes with 40amp cc, u may then be able to get 4 units of 250 watts panel

epsolar cc is decent, though fangpusen cc has a beta display and show more info than epsolar

pls confirm the amperage, 500ah wud be easier for ur cc to charge than 800ah, hope u know abt the c/10, c/8, c/12 formular for smf/flooded/gel batts
Re: Solar Energy, A Complement To FTA by Saipro(m): 12:28pm On Jun 06, 2016
RipVanWink:


yeah, cost is a big determinant of not building in 3 to 5 days redundancy as required, i hv a 24v 200ah batt bank in the villa, due to cost...i only hv half day redundancy .... only way i instructed them to stretch the run time of inverter on rainy days is to turn off the fridge/tv/fan....n use only lights....
in naija its difficult to have 4days non stop of badweather/continous rain...........even on cloudy days..the panels generate small power still
energy is finite, cant be created from nothing, apart from turning off heavy loads, there is no way to increase ur runtime...unless u want to invest in a device called sunforce...this monitors the irridance and lets u programme the load attached to it to run on sunny days/periods etc........
some high tech inverters might hv this as a built in function.

I'm telling you, the cost of redundancy of any sort is all but prohibitive. By default, if your system is sized for 50% or lesser DoD, you already have about a day's redundancy in-built (although it's actually good practice not to exceed 50% DoD rather than a redundancy issue). To use 20% of the bank daily in the tropics is perhaps unnecessary but the latest spate of bad weather (lasting weeks; the worst I've witnessed in my 14 years of using inverters) is worrisome and has got people with high redundancies smiling. I had to do an emergency upscaling of my panels by 33.3% to meet daily charge requirements while simultaneously cutting down on my loads. It's gotten that bad. Things seem to now be picking up.

Now that the matter has been laid to rest, I can venture some gleaned knowledge:
1. Charge controller displays can't always be trusted with regards to energy generation displays. Particularly true for Chinese PWM/MPPT.
2. The refresh rate of the displays vary and oftentimes, output lags behind input. You can verify by just spending a few minutes in front of the controller.
3. The longer the cables between the battery bank and the controller (and the thinner they are or the heavier the load), the greater the disparity between the apparent power at the battery end and the actual power at the controller end. That's where the voltage sensing cable comes in.
4. The expensive CC have a reason they're expensive. I as well own a Xantrex and a Midnite. Don't berate them. Having said that, suitable cheaper alternatives exist. EP Solar makes wonderful MPPT controllers with excellent DC-to-DC conversion and pretty good overall efficiency (of course never 100% but good enough for practical use). Just don't believe everything it displays. I had issues with mine and posted details of the issue on this forum a year ago. I still own one so I can tell you it works and does its job well; the problematic one was the exception to the rule.
5. Get a trusty voltmeter and a DC clamp ammeter as backup. They'll save you a lot of worrying over apparently puzzling and inexplicable phenomena. Like input energy being lower than output energy. And be sure it's a DC clamp meter. There are people on this forum using the AC version. Ain't saying no names.
6. BEWARE: Some CC leak power back to the panels at night, even trusted names and brands. If you're having inexplicable phantom drains, cut loads for on night and see what's going on with the consumption. Or whip out your clamp meter and check the cables.
7. A significant number of problems arise from loose connections and improperly sized or overloaded (thus damaged cables). Yeah, I know, you've checked the connections and cables a gazillion times. Before you say it can't happen to you, check again. I've had it happen to me a few too many times to ignore. These are connections I secured personally. Probably just one connection in nearly a hundred but I assure you that one is significant enough to bring the whole system down. And if your system is working fine, grab a wrench/pair of pliers and check your connections every few months. A stitch in time saves nine, probably a score.
8. All can't be said at once. More talk as more issues arise.
