A Nigerians buyer reviewed that it discharges the battery when there is a power cut. How did you go around that?

My primary 12V charger died after about 10 years of meritorious service. Not keen on rewinding the transformer nor tampering with the FETs (done that once before and it wasn't quite the same).

Any recommendations for something cheap and reliable? Needn't exceed 20A (max 30A). Currently rigged a spare 250W panel with a spare CC to help people maintain batteries kept with me.

I can confirm that the HA02 battery balancer works very well. Battery balancing has become a key part of using a large battery bank sustainably and even most Lithium BMS have some sort of battery balancing mechanism in their core design.

The common issue I see with all the people I have heard complain about the HA02 seeming to unbalance their bank is that they bought off AliExpress and/or from an unproven source . I have only ever used the HA02s from an Amazon seller called ZHC Solar - after many transactions, we took our business offline and so far so good he has never dissappointed. He was even able to point me back to TaicoPower his actual source - when I showed him AliExpress prices to beat down his quote he would shake his head and insist that it was impossible to sell the product at that price and make a profit if sourced from the original manufacturer.

I don't like the HA01 but the HA02 is designed very differently and it works well to maintain balance if used on a set of good batteries from the beginning.

I have had some units in use nearly two years now and all the banks are nearly in perfect sync. 0.1v difference between batteries like an installer here once visited me and showcased my setup.

Niyi, do you have this HA02 for sell, or if you can recommend where I can get it here, its urgent

The most important aspect (and one which is often ignored / sidelined) is getting a hand on how much electricity you consume and how much you generate. Its not about how many panels/batteries you have. Its simple maths. If you consume more than you generate, your battery would be the one to take the hit and make up for the deficit causing bad things to happen to it.

A fridge or freezer is just a load at the end of the day it uses watts.. this watts are of no difference from that used by your TV or any other appliance in the house. Yes Refrigerator uses relatively high watt appliances and in most cases represent the defining load of most offgrid systems. You can easily run a freezer or fridge on an offgrid setup once you have a proper plan in alignment with how much electricity you can generate while keeping your battery at a minimum 65% state of charge / 35% depth of discharge.

When I started my offgrid journey, I had just 480w panels, Yet I was able to power the freezer for a minimum of 4 hours a day while ensuring that my battery always get to float, and never discharges low 60% state of charge. This was possible because I did an electrical audit and rationed my loads using battery peukert effect to my advantage. My energy consumption gradually increased as my as my generation capacity increased, today I have a panel capacity of 1840w and I have included the fridge to the mix, both fridge and freezer run at a minimum of 8 hours a day - 08:00 - 16:00pm. An I have just 2 220AH batteries. My system runs 24/7 yet my battery voltage never goes below 24.5v in the morning.

The key is getting a hang on your load, spending time to make you loads more efficient (not just using so called energy safers, but actually checking the watts of your appliances. Watts counting matters alot)

designing your system to cycle at 70% battery state of charge hence they won't be any need to waste money/time/energy on unreliable low voltage disconnect systems. If your system is deigned around a low voltage disconnect, then they is something wrong with you design.

My Humble Opinion

I just stumbled on this post. I want to ask a question.

I am building a very small system....i am rarely at home during the day and so i feel my battery(s) will charge well during the day.

Panels are;
3pcs of 100w, with one salvaged 300w panel all in parallel (its a 24v panel tho, why not just add it rather than leave it idle).

200ahr battery; and a an average load of 150w through the night (max 250w briefly).

Since im not always at home during the day, can i get/add a very small chest freezer to my system? any idea of any easy-to-get brand? Say 100-200ltrs and very efficient too.

Hope my question isnt long and winded.

Thanks

You need to answer so many questions,
NO U CAN NOT ADD IT! (I am at home will not work o)
From d little details u gave. U have a 12v 200ahr and u re pulling 12.5a already(150w) instead of 10a(120w max, C20 rule). U now want to kill d donkey by adding small chest freezer. How long does the battery last over night?. Under 50%Dod, u can't do more than 7hrs, except u have started killing the battery already.

Note: why put a 300w panel in parallel with 100w panels, are u an installer?

Emerson bulk charger working great for years ! Works basically as current booster when needed ! Have a spare laying around for an interested buyer .. Snapshot below indicates paired charging with inverter 50a max charging current (throttles down as battery charges) ...

is there any more wrong in runing 2 x 250w panels in series to an mppt charge controller on a 48v inverter, my instaler is insisting there is no harm/loss of charging potential, i feel a 3 x 250w series setup is better, so as to have enough headroom to charge the smf batts.

what do u guys think?

You are right on the mark. 2 250w panels for a 48v setup is essentially running your mppt as a pwm. There is little or no head room at all and your system will have little tolerance for voltage loss.

You can be right IF and Only IF your mppt max voltage is 150V and not 100V confirm that first.

@Malevonent
Most 48v mppt have input of 150v. 250w*2 in series will perform poorly. 250w are usually with Voc of 35v while 200w are usually 42v.
So check what the Voc is to determine the optimum config

the make of the cc is voltron, voc max is 150v, so it can take 3 panels in series,the installer appears not so knowledgeable, i am beginning to doubt the whole installation, does anyone have the voltron cc or the manual....want to check the internal settings are set apprioprately
i met the setup on ground...so pretty much little i can do now

I have inverter that's with AGS slot automatic generator starter, pls anyone have idea how to install this on a disiel engine like mekano or perkins, do I need to build a panel for this or the inverter already have the panel inbuilt?
Note* the inverter is Mustpower

NiyiOmoIyunade:
No effects on battery backup time as far as I know.
I believe that using common neutrals increases the possibility of catastrophic damage in the event of a wiring fault - also most people do not obey the NEC code guidelines on how to properly size the neutral wire when doing common neutrals so if done incorrectly the possibility of overloaded neutral wires and wires melting and causing a fire increases.

Usually, no problem. Some devices in the house might have a "loop circuit" within. While not generally a problem, they give all kinds of surprises on occasion and can make troubleshooting for "earth leaks" a formidable task. Or so I've seen previously.

Hello guys.

My mum recently got a 1kva system and a 200AH battery. She wants to buy panels later this month, but she does not know if she should buy two 150w panels or just buy one 300w panel. By the way, what kind of solar charge controller will be needed for such a system ( 1kva & 2kva), and how much will it cost.

P.s. can one 300w panel charge two 200ah batteries?

Thanks for answering

A 50w solar panel can charge 8 numbers of 200ah, but the question will be how long will it take to fully charge it. To answer your question, the number of panels you use is dependent on two factors, how fast the battery drains and needs to be recharged (which is based on the load connected to it) and of course the number of batteries you are charging.

The more the load (bulbs, fans, TVs, etc) connected to an inverter, the faster the battery drains. Two 150w solar panels and one 300w rated solar panels are the same (if both are from same make and age).

BUT if I'm to hazard a guess without knowing the load, I'd suggest four 300w for two 200ah batteries or two for one 200ah battery.


As for the price of the solar panels, it is dependent on make and condition (new or fairly used). Wait, the marketers are coming


Charge controllers are two types PWM or MPPT. I think a good PWM may just do the trick. But if money is no object, get yourself an MPPT solar charge controllers as they are pricier.

Nice input ! Bottle of chilled beer for you ... If the OP hasn't purchased an inverter yet, I would have suggested our affordable hybrid specs. Nevertheless, if budget isn't much an issue, I suggest he goes with 40a mppt to achieve 2S2P config within safe 100 max voc. Secondly he can opt in for 30a mppt if his daily load isn't much.. There is absolutely nothing like spending on something and enjoying your investment .. Cheer's

Assuming C10 and no losses, A 200Ah 12V battery has 2400Wh nominal capacity. Useable capacity is 1200Wh.
You need solar panels to replace the useable capacity in the available sunlight hours.
Assuming 4 sun hours in Nigeria, 1200Wh/4h= 300W panel(s).
300W/12V = 25A. Some folks advice to not load your cc above 80%, approx 30A cc.

Any 30A PWM/MPPT CC should do the trick. It's max Voc will define how you configure the 300W array.
Whether it's 2# 150w, 3# 100w, or 1# 300w panel(s).

Even though you got a 1kva inverter, keep your loads below 240w.
Using the same inverter, for each 200Ah battery add a 300w panel and increase your max loads by 240w.
