Someone had it up for sale in this thread.. Hope you didn't miss that

I already ordered at ₦ 42,848.00 including delivery, which is cheaper for me.

Ok, this is noted

Valto:
ok. note it is PURE AC / DC. it can be plugged to light directly. they dont need ac adapter. it comes with remote and regulator. energy efficient and very low power consumption.

microgiant:


It is lifepo4.

I paralleled them with 2nos 150W panels connected to the SCC.

Is this for sale?

Did you buy it brand new on Ali express or you got it in naija?
How much is the Ali express cost for that size?

If na me I will trade-in this inverter to get another with verified lithium settings like sorotec, growatts etal so that u are sure of what you are using to eat your beta soup.

dejidotun2000:
Hello house, trust we are all doing great.

Does anyone here know the max charging current of the 5KVA, 48V ipowerplus inverter while charging from the mains ?

Also, does it have a dedicated lithium profile ?
I want to use it with a Pylontech UP5000 battery, is there anything I should be worried about ?

[quote author=olopan post=102940458]This is fine, as long as the genus inverter does equalization


Please, someone should enlighten me on the issue of equalisation above.

I don't know what else "lithium profile" on a charger mean other than setting bulk, absorption and float voltage to the same value and disable equalization. That is exactly what happens when I select "lithium profile" from victron charger. As to the fear of continuous float charges on the battery, the BMS usually does the remaining. When my lithium batteries enter "float" the current meters read zero.

So, if you have a perfectly good charger (inverter or Charge controller) on which you can modify the charging parameters, I don't see the need to waste extra money on any "lithium" profile, I honestly think it is a scam for manufacturers to make a little extra money on selling their inverters and chargers.

You are very correct, just get something that has an adjustable charging profile, that's all!

Ordinary Bench power supply will do the trick self.
Lithium profile
Even the lithium profile on Victron still needs to be tweaked..

Hi. Do you have DC standing fans also ?

Valto:
ok. note it is PURE AC / DC. it can be plugged to light directly. they dont need ac adapter. it comes with remote and regulator. energy efficient and very low power consumption.

At least two people on this forum do, niyiomoiyunade is one of them. Check his signature to see his setup.

mctfopt:
Genuinely out of curiosity, is anyone running ACs or AC off their renewable system? If yes, what is the minimum battery and PV they running it off and how has the performance being?

dejidotun2000:

yes it's available. 19000. it is a dc/ac 18inches with usb and remote (25w consumption on highest speed. can work with 12v batteries, 12v to 18V solar panels and direct to 220v utility.

I run 2 ACs, they are both thermocool 1.5hp, one is inverter AC and the other is normal. I currently have 280AH LFP 48v (not the nominal voltage) with 5.2kw PV and a Deye 8kw. They serve the household appliances not just the ACs

This is awesome to hear. The 5.2kw PV is it premium make or just Chinese type? I do see Deye online, didn't know they make really cool inverters. My neighbour just had these bad boys delivered.

280w X 9 - Sunfit panels
380w x7 - Prime panels

Both are made in china...Deye inverters has started showing up more in naija....I know someone locally who now sells 8kw for 860 to 880k

Your neighbor Sabi be that. Those looks like 280 or 300ah cells. You both Enjoy!

That's 280AH, he ordered 310AH again. In lithium we trust. Lol

guess it is 32pcs eve 280ah cells.. the 310ah should be CATL...

The 310 is CATL...you know your Chinese

This is an interesting design question - one that begins to come up more as we get larger and larger panel sizes e.g 385w, 435w, 535w due to tech advancements yet the traditional CC manufacturers are sticking to the standard 150v ceiling or you already have 150v CC on hand and unwilling to upgrade.

From the point of view of the charge controller, the VoC is a momentary value just before the internal circuitry engages and begins to take/make power from the panels.

A 3s config with ~49v VoC panels will work with a 150v capped CC in the following scenarios.

1) You are located in the tropics with ambients generally over 30°C - there is an inverse relationship between temperature and VoC so your observed VoC will be less than the panel spec at 25°C STC

2) The panels will mostly be at open circuit in the early mornings and late evenings - both of these times are associated with poor illumination so the reference VoC will never be attained. In the case of an afternoon disconnect creating open circuit condition, the ambient temperature in the tropics is high enough that the actual VoC is less than spec

In summary the fact that your ambient temperature is higher than reference and your illumination is lower than reference allows you to get away with a nearly 150v VoC on a 150v capped CC.

Should the day come when you have an 10°C ambient and perfectly clear skies and full sun - you may well brick the CC permanently.

If you installed in Jos for example or some parts of the North that get really cold yet have full sun and clear skies, you would have to do extra work so that the install stands the test of time.

ceaser:
Folks. Concerning the use of this for a 48v system, would it still be appropriate to go 3s, considering that the VoC per panel approaches 50v, making it around 150v.

Save the hybrid systems, most of the available MPPT CCs are capped at 150v max.

I continue to do 3s with high VoC panels with the Victron 150v CCs

The capacitors inside the Victron CC are rated for more than 150v, the ambient in Lagos where we do most installs is higher than 25°C and the available solar illumination/irradiation is less than the standard reference.

This is one of those cases where one is playing on the very margins of what is possible.

I once consulted for a site who used 4S with smaller sized panels because they were locked in with available equipment and number of panels - we used thinner cable and longer route than required to achieve a suitable voltage drop so that what got to the panels was well within spec. You simply have to understand the specs and tolerances well to play safely at the edges.

ceaser:


I thought as much. However it will be more revealing if anyone here had had cause to install these types. They will do peeps a lot of favour telling us their experiences and choices of connection.
