My inverter VOC is 145vdc max. Each of my panel VOC is 37.44. The Max I can do is 3s. 4s will be too much for the inverter

So get one more panel and run 3s3p, your current 2s4p may not be optimal enough

I think the recent increased penetration of the high voltage hybrids automatically made Ojesky think its one of those.
It will be good to state the inverter / CC specs when asking for assistance o. To avoid stories that touch.

Lol....I actually asked for CC spec in my original response to the Bro, unfortunately he didn't include that and I didn't pay attention to it either when he responded to me.
Meanwhile 4s 270 will definitely be of no use to high Voc o..... those ones are just warning up at 150Voc

Please house, is there a way to bypass the float charging in lithium profile of Epever Triron3210?

I learnt LFP aren't supposed to be floated, but the float voltage is set at 13.8v and doesn't work if zero (0) is typed in place of 13.8v.

I would like to know if this would have any adverse effect on the performance and/or life span of the battery. Thanks.

Is that the minimum it can allow? I now use 13.5v as my float value but when I had MPP which had a known float bug I used 13.8 then drop the voltage back to 13.5 once battery is above 95% SOC (it's automated). It's okay to float just don't leave it on float at high voltage for a long time.

Hmmm, are you sure of his inverter Voc?
Has he stated it before, guess i missed it.

Most common hybrid inverters have Voc of 150v, if so 4s2p on 270w panels will fry it. Best he buys 1 more panel to make it 9 and then do 3s3p

Abi his hybrid is the high voltage types that can take upto 450v, if so.. then line it up 8s1p

Better Advice check the VOC of the inverter before giving such an advice

If I reduced it, it asks to reduce/increase some other figures. They follow a certain rule and are set by default when you select the battery chemistry.

Floating starts only when the battery is full and is probably there until the sun goes out or enough loads to bring the battery back to charging State are added.

If you are certain that is how it behaves (as that's not the case with certain experts) set it to 13.5. You may go higher to say 13.7 if you do daily discharge on the battery

Does anyone have an idea with buying LiFePO4 batteries from China(Aliexpress).?Will one still need to.pay duty once it gets here?

I'd do that. Meanwhile, do you think I should get another CC?

I am on 2s2p 150W charging 12V (ie 12.8v) 200AH LFP with this CC having 360W as Max pv input.

Good day everyone,

A big shoutout to fastshipping's He contacted us around October last year for his home in Nigeria on how he can use Solar to power his appliances inclusive AC,

We did quite a lot of tussle between finding the budgetary solution that will still fit his needs, with couple of meetings we came to a conclusion.

Growatt Inverter 48V
Charge controller
Canadian panels
9.6KWh

Is that 4s3p config for the 48v system?

Peterlove11:

Yes even with load more than 1.5kw in full bright sunlight, the pv production is barely 850kw
2 Am using the inbuilt controller that came with the hybrid inverter. It's 80a Mppt

3 It's 48v 2s4p of 270w mono panel each

2s4p ke?! For a 48v system from 270w panel, bro that is suboptimal.

I have a 24v system with 320w panels (2s2p) and 350w panel (2s1p). The open voltage is around 85v to 90v and while on CC comes around to 70v to 75v.

From this, using 2s for your 48v system will give poor harvest for the open voltage will not approach the level necessary to power your CC to charge the batteries adequately.

Least you should go for with your 270w panel is 3s and 4s if you have a controller with open voltage approaching 180v.

Peterlove11:
.
You are right. It's actually 145v max. I think I will manage the pv production. Will augment with Phcn. I appreciate everyone contribution. Thanks

Change your config to 3s first before thinking of managing PV production, for you may end up getting an impressive harvest doing that that augmenting with PHCN may no longer be a strong neccesity.

Thanks for your feedback.

I think you got the strange figures because your input are not real world values.

Firstly, there's no way total startup power of all your appliances will be just 2000W while you consume 750kWhr in a month.

Secondly, it's near impossible for you to consume an average of 25kWhr in 24hrs(from your first input) and your night consumption will be as much as 24kWhr.

If you input real world values, you'll get real world answers.

You can offer where corrections is to be made if you notice any and we will implement it.

Thanks once again for your feedback.

Baba, 25kwh in 24hrs is very doable. Doesn't even need much to accomplish sef.

essegis:


Baba, 25kwh in 24hrs is very doable. Doesn't even need much to accomplish sef.

Are you saying that it's possible to consume 1kWhr in the day and 24kWhr in the night and your total appliances startup power is 2kW only?

Please kindly list equipment scenerio that can possibly make the above possible.
Edit: (Microwave, pump, air conditioner alone dwarfs the 2kW load). For you to do 25kW a day, there's no way you won't have some of those high energy guzzlers. So the 2kW total equipment surge is grossly under quoted.

1kwh in the day and 24kwh in the night is not what I meant. I meant as a total it is very easy to do 1kwh every hour for 24hrs to give 24kwh.

If you have one of there NEPA prepaid meters then you will understand what I'm saying better.
