Good day all,
please who have a review on this PowMr hybrid inverter?

earthrealm:


you have all this on just 8 pieces of 12v 200ah battery?.. omo u get mind...those batteries will die/get weak within 1yr, seems you are not knowledgable and fell into the hands of kazeems installers. like the one I saw on Instagram, a so called experienced installer with over 400 followers, hooked up a 1.5hp sumo on 2units 12v 200ah battery and 24v 5kw inverter...and was bragging, on how rugged the inverter is ..... an less than 2 months I give such a setup, b4 the battery go die. lead acid battery is not designed to carry such humongous load.

back to your question your 8 batteries if in good health can only carry a max of 1.6kw, so you need to ensure your panels would bring in the balance of 3kw....and also because of the varying weather/suns intensity..you may need up to 6kw panels to ensure you are sure of producing average of 3kw all the time......then the wahala of this design is that you may also exceed your battery acceptable charging current, likely 20 or 30amps.......unless its special agm that you can do 60amps.

lastly for you or anybody running or planning to run such a huge load... best you for lithium battery...or 2nd best option, these 2v 1000amp or higher battery

I have returned the inverter and he said his supplier said 4.2kva eco will be available tomorrow... Please can you help me snap the inverter and the carton so that I can inspect it carefully before I accept it

AmakaRuby:


That means I will have to open it? I'm afraid that if I should open it and it isn't actually 4.2kva, I won't be able to return it to the seller

AmakaRuby:


Yes, I requested for 4.2kva and was given this

AmakaRuby:


Does the welion 4.2kva inverter come with 120a cc or you bought a different cc? Asking because the one I bought is written 80a cc

Na price they kuku make man give customer tubular quotation. Once they see the price like this, them they always choose tubular.. Na to they make them see the benefit of lifepo4 now ooo i go they do abeg.. Happy customer na happy me oo wallahi.. This back and forth done drain me.. 😔

Drgreatone:

Telling him to buy a 20amp mppt isnt helping the customer too. The least I'd recommend is a 40amp mppt or better still get the powmr pwm 60/80amps which has lithium charging abilities and is cheaper. U can check jumia for it

swagifted:
National grid don collapse again... Who knows how long this one will last

Drgreatone:

Start by telling is what ur existing setup is? Why do u want to do a 20a charger when there are higher specs?

dollarnaira:


In as much as I detest tubular batteries here is a personal advice.

As told by someone above get an external ac charger to charge each batteries full at lower amp in order to desulphate each.

Tubular battery is by luck. Probably you bought brand new ones that had been in stock for too long and sulphation had set in already. Desulphate and enjoy. The charging profile of tubular is annoying.

AVOID TUBULARS AT ALL COST.
Good batteries go beyond size.
Get ordinary 100a LifePO4 and experience peace of mind biko.Look beyond the miserable deceitful 220a on it. All installers will continue to have problems if they were still stuck with tubulars. Replacing batteries after 2years sef is bad on its own.

A friend of mine had all 4 tubulars bad after just 2yrs. Just imagine! My ordinary 100a 12v system is far efficient than theirs big time with my total load higher than theirs. While they are planning to replace theirs, I just got started!!! Life is too sweet with LifePO4.

I would had rather extract laptop lithium ion batteries than the best tubulars with pampering of 50% DOD.

Are you in Lagos?

Eeyah, sorry for the stress bro. Had same issue in 2020 when I newly got introduced to the world of renewable energy. My batteries Couldn't hold charge for long, will run down very fast, and they are all new. I Called the installer,but he couldn't profer a solution. Luckily I discovered this forum.
To cut the story short, my Bluegate inverter was the culprit. Couldn't charge my batteries as per manufacturers prescribed setting. To recover the batteries, Had to trickle charge the batteries for days(I used less than 5amps, mostly 1amp charging) without using them. And eventually, they recovered. Tubular batteries, especially those that have been in the sellers shelf for a long time before being sold requires equalization or desulfation before use. The internal resistance would have increased Overtime and won't be able to accept charge as it should.
My batteries are now in it's fifth year running strong.

Trickle charge them with the Charging voltage set to around 30v. Lets hope they recover. If they are new, they should recover.
I am not an Authority in this, am only speaking based on my experience

Dam5reey1:

Their usage pattern is the cause they are deep discharging the battery.

11.99V and 10.99V is a sign of bad batteries.

Get them a minimum 5kwh LFP pack and have peace!

ok panels check out, WELION inverter, you need to put it on flooded battery setting, not default or choose user and set bulk to 14.7v and float to 13.8v........and activate equalization immediately and set monthly equalization too for 4hrs at 31v.

am assuming the batterys are brand new, so electrolyte SG is correct, just that its not being charged and mixing well cos of the low/wrong voltage. higher/correct charge voltage and the periodic equalization shud sort you out real quick..

your leaving the inverter on default is the likely cause of this issue, and most average installers are guilty of this as well.
also the pump load is a bit high, but if you run it only during the day, with solar panels kicking in juice, you shud be fine

Dam5reey:


you are running about a 1KW load on 2 Tubular batteries. this is a stale story.
these batteries are for light loads.

U DIDNT MENTION ANYTHING about solar panels?.
max load you shud put on the system without damaging it is 20amps x 24volts wch is about 500watts....that pumping machine, have you checked the actual draw?..same for the freezer.

what of battery charge voltage algorithm...what voltages did u set the inverter to?..abi you just left it on default?
check the SG of the battery electrolyte with a hydrometer and be sure its good

Drgreatone:

What type of inverter are u using and the nos/type of panels u used? Suspecting sms though. How are u sure they are not putting extra loads and not mentioning it. Its either that or the batteries aren't charging well sha

Dam5reey:


Most of the time Energy ratings on Appliances are peak power and not continuous power, especially for Heating and cooling elements.

The best way to understand your usage is to add an energy meter, Smart plugs, and a watt meter plugged it will calculate your usage.

For the sake of a rough estimate, take the 270w as the power.
270W Plus 30W inverter consumption is 300W rough estimate.

your 12V 100Ah is 1280wh = 4 hours usage
12 200Ah is 2560 = 8 hours usage

Una good afternoon here bosses.. Abeg make una help me with the wattage of this Samsung fridge/freezer pls..Also, how long will a 12v 100ah lifepo4 or 12v 200ah lifepo4 battery last with it after sun pls let say after 6pm.. Wanna see if we can move the fridge to lifepo4.. Journey to lifepo4 done one begin be that..
