Don't think that's true either. Prices are identical, maybe just 20-30% more expensive for 48v.

Please capacity of solar panels required and the charge controller?

Drgreatone:

Why dont u get an installer and av him give u quote unless you are market savvy. Get a 60amp or preferably 80amp solar charge controller, panels from verified sellers here (2 450/550w panel depending on ur charge controller VOC). A 4mm solar cable wud do since u doing series, dc breaker and spd, combiner box, aluminum profile, nails, bolts/nut and washer, flashband, nails to mention a few.
NB: Does ur inverter av a lithium charging profile? If not, u may be totally dependent on solar for charging

Experts in the house, kindly proffer your advice concerning my inverter setup.

I have a 3.5kva SMK Inverter with two pieces of Cworth Energy 2.5kw Lithium 24V batteries (as seen below) and four 380w PV panels. On Wednesday afternoon, the inverter let out two loud sparks and started displaying error code 09 (this would be the second time within three months). A technician suggested that the inverter may not be compatible with the lithium batteries and suggested I replace it with a 3kva Felicity
brand.

Does anyone have an idea on which inverter brand will be most compatible with the batteries?

Thank you.

Drgreatone:

Its more than that ooo. A 48v100ah wud be like extra 80 to 100% of a 24v100ah battery

Alternative inverter brand will be based on your budget, so please share the amount you're comfortable spending on a new inverter first.

Secondly, get Ur installer to separate those battery cables, let the positive be on one battery and the negative on the other, this will aid even current draw between the 2 batteries connected in parallel, as it stands, battery 1 is taking all the hit and will charge and discharge faster, while battery 2 is in limbo.
If you have a high influx of current higher than the BMS capacity, then Ur battery BMS may clip the current to save Ur battery and that might be part of your problem.
Preferably, get a busbar, connect both batteries to the busbar independently with equal length cables, then connect to your inverter from the busbar, that would be the ideal approach and will aid balance out Ur batteries too.
Just my 2kobo.......

Good day my good ppl.. Kindly advise, which should i get out of the 2..need something that work well and also support lifepo4 battery as well..cause the guy plan to get lifepo4 later.. can see on the spec it does support it... But i need you guys option on which to go for.....Thanks.

Oga boss na money oo.. You gat to help customer manage what they have to achieve what they need..what he has on ground is 200w 12v panel x2 100ah block battery 60a pwm 12v serchet inverter pure sine wave that all.. There is plan to upgrade to 12v 100ah lifepo battery in future. So he wanna get cc mppt now then battery later... he should get a 60A, as 20A is small for his 400w panels

Drgreatone:

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

AmakaRuby:
Good day, pls is it advisable to buy inverter from alibaba?

Don't waste your money going to buy another Inverter. The problem is that the IN-RUSH Battery Current damaged the DC Bus Gates of your inverter which is likely to continue even if you buy another Inverter. That spark your noticed was supposed to be absorbed or suppressed by the Pre-Charge Resistor first and softly starts the Inverter LV DC Bus Circuit.

Newer Cworth Batteries has an RJ45 type Pre-Charge Resistor that you can plug into the RJ45 Port to limit the In rush current. Some other Lithium Batteries has the DIP Switch type of this Resistor that you can toggle to on and off.

If your Battery has an RJ45 Port, I would suggest you approach Cworth Service center to grab this Resistor. If your battery does not have an RJ45 Port ask them for a Pre-Charge Resistor or you can buy one to retrofit in your battery.

Every Installer, DIYer, etc is supposed to have this Resistor because some Warrantees does not cover damages caused by In-Rush Current. Take note.

You can google how to protect your Inverter from in-rush current for more info.

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

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
