A lot have been said already; an amateur should certainly certainly go for ready made, while DIY amateur like you and I can couple their cells. I suggest getting the bank from the person I got mine from, it's a good way of starting and learning the connection in a DIY way (the pack can be easily opened).

I will suggest that the more fewer cells the better so if it's a single 300AH cells then go for 16 of those. The ANT BMS has a Bluetooth option for Comms. In terms of brand, well.....China is still the best source for bad and good cells as they are most experienced with lithium. Sinopoly, CATL(if you need a strong enclosure) are fine. Mine are Eve prismatic cells and they perform well.

Thanks for the explanation, he says he has eve 105ah cells now.

@ ceaser, so you can actually mix different packs from different sources, without issue?.
@ tonydiddy, nice.. i expect you to hit upto 350w or higher on sunny days, if you turn on your house loads
At least upto 250watts.

This your Sorotec is a beast, wonder why peeps never buy am. The inverter make brain

ojeysky:


250A charging ? Okay you rightly described it.

That's the dc input, the camera didn't capture the dc output side

That's right actually I didn't pay attention to that part, so can @mctfopt provide the charger section so we know whether it still retains its name tag

We were waiting for you to put money on it, really anyone that wants a MPP like features they will get it on that sorotec so I certainly recommend it to anyone shopping for a 24v hybrid that has muscle to carry up to 4.5kw PV

Ceejay80s. First, I want to appreciate you for opening this thread and your efforts.

We did business over 3 years ago. You helped me to purchase my entire DIY unit comprising of UPS, 30amp smart charger, and a 200ah battery. I used that unit for about 2 years before the battery packed up.

Ceejay80s and to all the gurus in the house, I'll like to know what kind of setup 500k will give me.

Note: There's no electricity in the area I'll be relocating to. So, I'll be leaving 100% off grid until more people start living there.

What I intend to power. 1 deep freezer, 1 standing fridge freezer, 5 wall mounted fans, 2 LED TV sets, 1 1200w iron, and general LED house lighting.

Priority goes to my fridge, freezer and house lighting.

Please, I'll love experts in the house to help me. I'll also like to ask. I am yet to wire the house. Is there any need to do a separate wiring for solar and another for NEPA?

Thanks in advance.

Hello house, I believe this guy needs help from the section. All inputs will be appreciated...

NB: Pls quote his enquiries and not mine

Hello house, please pardon my ignorance. Does one require a charge controller for a hybrid inverter?

no

after two straight days of relentless rainfall, the sun came out in full force yesterday.
it was happy days at last as modules greedily pumped out juice after juice topping
almost 60kwh harvest as at sundown....
...the sun truly is the answer!

Valto:
no

Thank you.

Yes if the inbuilt charger controller cannot serve the total PV you intend to put on it

yeah, am a 48v man, planning for a huge upgrade next year, as i fully switch to lifepo4, got my sights on 5.5kw 48v SOROTEC, OR 3.2KW if my money no reach. all these inverters just dey copy themselves. kiekies phoccos and sorotec are very similar, except the hefty price difference, they have same form factor, down to the T, similar software as well, reminds me of powmr and makeskyblue CC, na so dem dey, only time will tell who copied who

They copied each other, but I'll still go for a Makeskyblue. I've seen it withstand abuse that will kill other charge controllers, eg someone once connected 3.2kw @24v to the SCC. SCC just stopped giving output. Only to start working when the panel was reduced to 2.5kw! It's a lil monster.

I agree most of these inverters from Growatt, MPP all have similar features, just chose your poison

Hello GeorgeD1, thanks for this thread. I spent all night reading from page one. How has your system been from day 1?

Using your calculations on page 1, I came up with a minimum of 12kwh as my energy requirement.

What's my best bet with a budget of 500k for a start? I can lower some of the load. Thanks.

Hmmmmmmm, I do think the market perceives a clear quality differential between the European origin Steca and Phocos vs Axpert and it's Asian clones.

The EU origin products are perceived to be more robust, stable and with better features overall.

One of my biggest issues is in-country aftersales support and parts when the product eventually breaks. I don't want to be waiting on replacement boards or parts to arrive.

Uncle George long time no see/hear

What is your battery/panels setup like now.

So that people like us can grow up to be like you one day

Apart from felicity I don't think any other official aftersales support outlets exist for the rest; including the MPP, phocos and the big wigs victrons, magnum etc. So replacement parts process will be similar for all of them when the need arise.

What is only debatable is durability.

brother,
really its been a while. though i may appear to be absent from the thread at times, my spirit, my soul still
breathes solar.
i tactically stopped making reference to my system size long ago in order not to appear to gloat. some here
might even misinterpret it as showboating. even the solar harvests that i post from time to time is just a way
of encouraging a few of us here who still look at solar with hidden doubt, not too sure of its possibilities. it's
my own way of saying, "hey, it's possible. solar is real".
that said, i have a very robust system comprising 48 solar panels total nominal capacity about 15kw. batteries
used to be 12pcs 260ah zenith lead acid totaling 780ah until earlier this year when i did an upgrade.
i will be posting details of this in the next few days along with pictures.

Sir, just open an electricity distribution company already!

lolz bros! this is still small nah compared to the system size of other peeps.
i still be learner where david poz and co dey oh.
i believe system sizing should be on as needed basis and each home have their
own peculiar energy needs different from the others. so for instance, as a single
person living alone, i might get by with as little a system size of 1.5kw but a
guy with large family and having a lot of critical loads to run will struggle with
a system 5 times that size.

@ ceaser, so you can actually mix different packs from different sources, without issue?.

I did o. Coupled two 12v 120ah from different sources in parallel. The two na LFP so I wasn't worried.

In fact, I have a DIYed a Li-ion 18/6/50 pack of 7s 24v 38ah connected in parallel to a 24v LFP for about a month now. Back has evidently increased.

The downside I foresee is that the 18/65/0 pack may not charge fully (recommended 29.4v @ 4.2v per cell) because of the CC setting which I have programmed at the recommended for the LFP (28.8v to 29v). The Low Voltage Disconnect for both packs is at 24.2v which is well above the allowable by the BMSes of both packs.

Battery less, specs not bad but a very untested brand.
