Good evening everyone, I want to do a little setup for laptop use only on a very low budget.

I plan getting
1 150w pannel
50ah lithium
And lithium charge controller
I will use UPS as inverter

main concern is on the 50ah lithium stuff, pls I need advice

I've gotten the needed information concerning electric fence.

Good morning the great community.

Pls can more than 8 Pylontech be made to communicate with inverter (Victron GX) without the Pylontech Hub?
The plan is to install 10pcs of US2000, I know 8pcs makes a loop, is there a way to work around this without installing the hub, will the addressing help with this or the hub is a must.

Appreciate all experienced seniors to assist.

If you are buying the latest US2000Cs or US3000Cs then you can parallel 16units of these without a hub.

For the older model US2000s and 3000s you will need a hub for more 8 units in parallel.

The work around is to connect all 10 units together via the short power interconnect cables and long power cables to bus bar. For the comms you will have 2 sets of batteries - a group of 8 where the master is connected to GX and another group of 2 which will standalone and only connect to each other. You ideally want to make sure all 10 batteries are around thesame SoC when coming together. The group of 8 connected to the GX will drive charging, discharge cutoff and comms for the entire system.

The tradeoff is that the max BMS driven charge rate for the system will be set at 8/10ths of what is possible and your dashboards on VRM will report 8/10ths of the total power out of battery but SoC for all batteries will stay in sync.

Ultimately, a hub will be needed to drive the whole system elegantly and professionally.

Oga Niyi,

I am so grateful for your detail explanation and display of vast knowledge, I know you are always providing selfless assistance to everyone on this forum, may you go from strength to strength and prosper in all you do.

In the interim due to the cost we may first go with having the two standalone, while we make a plan for the hub when there is resources to complete the rest 6 to make the second 8.

Thanks for enlightenment, we will be glad if you do be able to setup and provide training sessions, I know most of the people on this forum will be interested.

MontyNG:
Yeah I was doing that... But I can't imagine that will be good for the compressor. Did some research on it and these ACs have a "power down" routine which it wouldn't go through if you automate using the socket rather than remote.

I have something similar to the sensibo where I can switch on and off with IR and and change temp. But that didn't work well with the Hisense/LG ACs as there was no way for me to know the current state of the AC.

Works on LG GenCool 2 series

NiyiOmoIyunade:
Yes flooded batteries indeed exhibit lower voltage than other lead acid chemistries while at rest and at work.

However at 58v you are not charging your batteries to full. In general flooded batteries need to get to a minimum of about 14.6v per 12v battery i.e 58.4v for the battery pack. Ideally they should absorb at 14.7 to 14.8v per 12v battery which is a range of 58.8v to 59.2v for the battery pack.

Every month or so, you need to equalize the batteries and get them into the 15v per 12v battery range

It will be useful to read your battery data sheet (some info should be on the battery case) and adjust charging parameters accordingly if your inverter is capable.

If at any point in troubleshooting , the dealer swapped out or topped off electrolyte, then you are in a delicate place as they may have used too strong or too weak of a mix - an hydrometer is your best friend to know the SG and SoC of your batteries and inform your next steps.

Temperature monitoring is however crucial to their longevity. If your inverter/charger can to end-amps cut-off, the better

mcTrinity:
This is soooo wrongly wrong boss... The wrongness of this statement cannot be overemphasized!!! Lolzzz
On a lighter note...

For 4 years plus, my PV Array setup is split into two: East and West. Even with fridge, TV, fan ON, battery can still float around 6:10pm, depending on sun intensity of course. You can NEVER have that with South or North Orientation, irrespective of sun intensity

That Sunset charging is usually very advantageous...

I mostly split Arrays for clients into South and West; or East and West... Other times, I just allow everything on the south. But if I must split, West MUST be a consideration. In fact, I split because of that West Orientation; that sunset charging helps the battery a long way through the night. Only few times have I used South and North due to constraints

So, if you're going for single PV Array on one Orientation, definitely South is priority... If you're splitting into dual arrays, West Orientation is inevitable; i.e South & West or East & West.
Cheers

Edit: I see Oshomo12 and Dam5reey already reacted to that... Cheers

The Tropics are a wonderful place to be with regards to solar energy generation. South-facing panels anywhere between 5^o and 13^o inclination would give you the best of all worlds! if not for grime settling on the panels, laying them flat might be an all-around winner. Your points are however quite valid.

My biggest disadvantage with lead acid batteries(I'm using 24v 220 luminous bought 3 years ago) is with the charging current. I recently increased my panels to 340w *8 (2720w) and the charging current I see sometimes is scary sometimes getting up to 40amps. I reduced it initially to 30 amps according to battery specs and my load which is just 2 tvs a ps4, dstv and a fridge and freezer, but I seem to seem to be wasting solar power so I increased it to 65amps. Guessing with this my batteries won't last long from amps overcharging. Well time to start saving for the inevitable or is there a work around?

More amps more joy for Lifepo4 users..

65A is nothing on a 24V 200AH cells..

Reduce the current to recommended Charge current, only workaround, Else start saving for another batteries.

Yea i guess so, but I've made up my mind. Let's see how long bulk overcharging tubular batteries will last before it gives up. The small hope is when it gets to absorption, charging amps reduces

if you have a solid cc like the morningstar, there's no big deal with this actually.
the charge controller will dial back the amps and only allow what the battery will accept
pass through, unless your settings are terribly wrong ab initio.

Yea I understand but it will take longer to charge the battery and with this rainy season and unpredictable weather I prefer to get the amps I can get with little time.

isangjohnson:
NB: Batteries are tubular.

Pv Array 1 will face south while Pv Array 2 will face west in diagram one and two.

The second diagram are to be installed separately.

In the first diagram, I intend to connect the output of the two CCs in parallel to the battery bank to work in sync.

QUESTION: 1. In the first diagram, can Pv Array1 and 2 charge the battery bank simultaneously?
2. At what point will I allow one array to sleep?
3. Is installation of HA02 really necessary since monthly equalisation of these tubular batteries are mandatory?

Your advice is highly appreciated all

i see a lot has been said already on this.
1) the two arrays will charge your battery bank simultaneously. there's absolutely nothing wrong in installing your panels
facing west as long as they're not the only set of panels you have.
personally, i have west facing panels and to my surprise they seem to outperform my south facing panels which is still a
phenomenon i'm trying to understand till date.
2) you don't have to worry about one array going to sleep or whatever. your cc takes care of that
3) i'm not a fan of balancers (never installed one) and i rather think they're overrated. if you do your basic wiring properly
you won't need one as your batteries will always be in sync.

It really depends on your budget and need. Generally you want to do Lifepo4 but you may go LTO as well. DIY approach is cheaper but may lack certain esthetic from packaging to certain bells and whistles. However, it gets the job done if done properly
