Good day House.

Please I need a 4kW - 5kW 48V Inverter (not necessarily Hybrid) with at least 60A AC Charging Current.

Get across to me here or send me a mail on pharyntee@gmail.com

Appreciated.

Don't waste ur money on solar inverter. If you are satisfied with ur current inverter performance then buy only solar panels and an mppt charge controller. Connect these to ur current system and you're good. Same thing I am currently doing.

Hello gurus, what solar inverter brand would you advice one to get. I am looking to upgrade my current battery-only setup to a solar + battery + AC setup.

Thanks in advance

Avoid Chinese inverters...they are cheap and strong inverter-wise but very poor charging which will ruin your batteries at d long run

try MPP solar incase you have means of importing ( made in Taiwan) - they have models from 60 Amp upto 120 AMP on 48 V the only inverter I found in market with such a high charger rating -http://www.mppsolar.com/v3/pcm40486048-series/

available on aliexpress with Nigerain Naira cards also - http://www.aliexpress.com/store/all-wholesale-products/629424.html?spm=2114.12010108.100004.3.4Lnz3j

Many vendors in Nigeria such as Zinox(ipower) stick them with there own branding although the specs vary acrosss models in terms of amps so check when buying .

alternative on Jumia ( dont know the brand but MPP solar confirmed it is not there models and china copy) -https://www./protek-5kva-solarhybrid-inverter-4110770.html

Alternatively PRAG also has different models but for 60 amps you might have to choose 7.5 KVA or higher model

From my experience, those Chinese inverters with transformers don't have this charging problems but those light weight nontransformer types ends up messing ones battery

Thank you for your input, The items powered on are 1 tv, 3 fans, charging ports for 2 laptops, 6 energy saving bulbs. I believe with the system i have, i should be able to enjoy electricity 24hrs a day.

Please enlighten me.

first can you tell us your PV input voltage? and secondly your cc will see your battery empty @48v so what you are seeing on screen is correct this does not mean your inverter will not work. Third I guess you're still using the default settings? Cos at 57v your flooded battery is not charged. You need to tell the cc that your battery is flooded so as to push the battery voltage to 59v. With the default settings the cc will not equalise your battery

If i am to setup a 1KW solar panel, can i use say 3kw from this setup if my inverter can handle 3kw. I am trying to understand if the panels charges the battery and supply power to your load and you a limited to max rating of your panel or it charges the battery and your load is limited to the max rating of your inverter.
Thanks in advance

You panels charges ur batteries so the load does not directly burden d panels but your batteries so that the maximum load you can power depends on ur inverter capacity. However with solar or inverter, u want to reduce ur load as much as possible to have good benefit from it hence d advocacy of low energy appliances.

which inverter doesn't have transformer?

JUO:

Please chip in.

Does this mean i can practically have a 1KW Solar panel + a 3KW inverter with good batteries then conveniently run a 2KW load without frying anything?

Basically your panels charge your batteries through the charge controller. What determines the power you get at a given time is the capacity of your inverter and the volume of juice (current) the batteries can supply to it to do its work! Your panel sizing now determines how quickly you can replace the current being drained from the batteries.

There is a reason the manufacturer of the panel say your solar panel can last about 5-10years on 80% load and 15-25years on 20-30% load

I know the average life of solar panel is 25years. Kindly provide a link that says the lifespan is dependent on loading or a link to show the % you shared. Thanks

I would avoid MPP solar Inverters. There are known to break down after less than a year of use. Video is all over YouTube. I would recommend Axpert solar Inverters which is actually what zinox rebrand as Ipowerplus. It is very popular in Australia and south Africa

Thanks to Richmond, my trojan T105 is now 2 years and is still going strong. Surprisingly my inverter has never gone off since I bought this hard dieing battery

Most of the so called high frequency ( transformerless) inverters breakdown because people don't look at surge capacities- High frequency inverter have much lower surge capacity best suited for light duty ( lights- fridge , inverter aC ) if you want to load like AC or motors give 2 times the capcity up in your inverter.

Another common mistake I have seen people making in general is using wattage as a guideline . It comes from long legacy of grid not caring about the reactive component . your load composition will decide the KVAR and sometimes a 4 kw load can actually mean more than 5 KVA rating

Personally I a,m enjoying them in 3 separate installations without any issues

Thanks so much for your patronage .... We now have same 12v 220a tubular batteries in GENUS brands .. Thanks !

Thanks everyone for the replies...

Today was a bit cloudy and no sunshine... How much power did you generate today from ur solar panel.. What happens when the rainy seasons fully kicks off?

anyone in the house, please help...
1. I have 2 No's 180W/24V solar panels.
Vmp=36.72V
Imp=4.91A

2. I have 1 no 200W/24V solar panel
Vmp =34.56V
Imp=5.71A
3. 2.5KVA/24V Prag inverter
4. 30A/24V solar PWM CC
5. 2 luminous 200AH /12V batteries

expected load is 360W to run for 6hrs each day

please, for the solar panels, what's the best way to connect it and how much power (Pmax) can I get all things being equal given the panels have different specs.

also what's the best type of wiring to use...6mm or 4mm

I am asking all this because where I reside, you find a lot of people parading as inverter specialist but in actual fact, dey are technicians with limited knowledge. intact a schematic diagram of d connection would be appreciated.. thanx...@richmon74, @kiekie1, @juo and all my ogas in d aus.

Your best bet is to connect your panels in parallel. connecting them in series is a no no due to the difference in vmp. in series connection you are as strong as your weakest link. The panel with the lowest watt can drag the whole system down. In your case parallel connection will see you have about 11A IMP and 34.56v

The second reason is your pwm controller which does not perform well when there is a very high variation between the panel voltage and the battery voltage. series connection would give u a max vmp of 68v compared to the 24v of your battery system. the pwm would hence be able to use just half of the electricity generated from your panel hence in your case series connection would mean your pwm can only use about 34v from your panel.. (This is where MPPT controllers shine, an MPPT controller would allow you connect your panels in series to a voltage higher than your battery system hence an MPPT controller would take the 68v, feed your system with about 28v needed to charge the battery and convert the rest to current (amps)) so in future when you want to upgrade your system, first thing is to get an mppt controller.

3. 2.5KVA/24V Prag inverter
4. 30A/24V solar PWM CC
5. 2 luminous 200AH /12V batteries
expected load is 360W to run for 6hrs each day

360w * 6 = 2160 / 0.90 (Inverter efficiency) = 2400w / 24 = 100ah which is within the recommended 50% dod for your battery. The question is can you generate 100ah daily to replaced what was used? I doubt your pwm controller can guarantee you that. so you might have to supplement it with a generator to charge the rest otherwise u would end up with a deficit where u are unable to give back what u took from the system.. leading to u been unable to fully charge your battery

also what's the best type of wiring to use...6mm or 4mm

Wiring depends on the distance between your panel and your charge controller. DC is low on volts but higher on currents, low voltage does not do well over long distance, it faces resistance which would lead to losses. and because you have little choice than to use a parallel connection with your panel, your voltage would be 34v. has such you have to ensure the following:

Your panel most not be too far from he controller, the distance would determine the size of your wire. Here is another advantage of MPPT controller, it can allow u to string your panel in series thus increasing the voltage allowing u to save cost on wiring because the higher the voltage the lower the resistance.
