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

JUO:
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

please give a review like Richmon did (can't remember the page) lets see

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?

All you good guys, can't name you all one by one.

Thanks in advance.

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.
juo kindly review ur post...

Anyone using this epsolar 45A or 60A mppt controller? Is it a good substitute for the more expensive American products like Outback or MorningStar?

Thanks

JUO:
super device believe me you won't regret getting one. Suitable for any kind of battery

mank1234:


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.

DMerciful:
40a epsolar is enuf for him at 55k(aliexpress.com), he can channel d rest to buy 200w*4 panels

RipVanWink:
@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

Good morning guys. Is a 40A CC good enough for a 1000W solar panel with 24V battery backup. The calculation puts the requirement at 41.67A or do i go higher like the 45A?

chris81964:

More than enough. Depending on your battery type, you will see about 28 to 30 v during the charge cycle. I have 2 kw on 24 V 60 amp controller. Works fine

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.
