I would be brief because I'm out of time and need get back to work.

Size of cable / wire doesn't necessarily affect current draw much. using properly sized cables is better to avoid wastes of current in form of heat (the wire go dey warm/hot). In fact, my guide is - the Wire is NEVER too thick AS the Thicker, the better.

As for increasing the size of solar panels, if you could afford such, please do because again to me, Solar panels IS NEVER too much. If excess, then less stress is on the batteries during sunny hours.

As for your pumping machine, what exactly are you doing with 2HP pumping machine ? In most residential houses, 0.75HP (less stress for solar system) and 1HP (equally less stress for solar system + PUMPs faster than 0.75HP) is often enough.
I'm sorry but I'm in a hurry to reason so make I allow others add theirs.

peterpeteru:


I see. I currently have 4 300W solar panels, do I need to add more?

I read somewhere on this thread that transformer based inverters are power hog, that they drain battery juice on their own. Is that true.

in your case, would suggest you inbhcrease THICKness of the wire, and also increase size of your Solar panels.

Reason to increase Wire thickness: When you increase thickness of the wire, or can confirm that when it's working, the Wires are not Warm / Hot, then you have eliminated WASTEs and reduced chances of fire accidents.

Reason to add More Solar Panels: With more panels, you get more Voltage and/or Current, hence during sunny hours (during the day), there would be less stress/demands on your battery bank. of course during cloudy annd rainy days, you have lless worries.
Now please ensure you always use MPPT charge controller when ever thhe Size of your Solar panels is much excess relative to battery bank. This is because with PWM, the difference mostly is wasted in form of HEAT, but when paired with a good quality MPPT, those differences ain't just burnt as heat, but converted and fed into the battery. For ma eye, I see PWM as a simple resistor circuit.

odimbannamdi:


Charge each battery to full capacity individually, then test each one at a time using ONLY a 100w yellow bulb connected through your inverter and let's see how long it will last. Preferably, get this type of standalone small digital voltmeter (costs around 1500 at Arena), connect to a battery at a time, during the test to help you see how the battery voltage drops. Independent voltmeter tend to produce an unbiased result.

Also, what kind of inverter do you use? Can you snap it and send to us? If it is a transformer-based inverter (those bulky type that typically has a charging function), there is a high chance that the inverter is also consuming energy while inverting. This could be as high 20/30w, which isn't ideal given the size of your setup.

Meanwhile, please desist from discharging your batteries down to 11.4v. You will kill the batteries before you know it, and considering that they don't look like durable brands. The minimum you should recommendably do is 12.0 (which corresponds to 50% Depth of Discharge [DoD])

Hello famz, GD

... I was sent these photos of my CC from home. Blue blank screen.
There were records of multiple lightening cos it rained.


... Are my fears confirmed? If yes, is there a remedy? (Other than full replacement)

Increase cable, energy saving is better than energy generation

Disconnect any terminal of both pv and battery let it go off completely den reconnect.
It will come up.

Thanks for the response. I guess i will do both. But one after the other.
As for my pumping machine, the depth of my borehole is 370FT. So a 2HP pumping machine was recommended.

Omo, professors don plenty pass student for this forum o.

I have used and installed and worked with "sachet" inverters and "transformer ", I still prefer the sachet ones oh -- atleast for my needs; which include a 1.5hp inverter ac.

I had a sachet inverter that took in water like a fish, dude kept working. I didn't appreciate the hell it went through till the day I was around and there was a storm and I saw how wind blew torrents of rain unto the inverter...I come de feel like one kain heartless installer . Infact the two cooling fans died with months apart and I was wondering what was killing them. The inverter overtemp protection worked everytime!!

The only part I miss from transformer types is the ATS, but again I'm probably 95% offgrid, so?

I have currently upgraded to a 5kw sachet but with better protection from the elements, and it's been working 24/7.

Even, if e die e no to cost to replace, compared to the transformer type of same capacity.

PS: I don work with some premium brands too, so I have a little experience of both premium and not so premium and basic.

bassdow:


Not saying they ain't Strong enough, just that when e [Finally] dies, REPAIRs is difficult, if not almost impossible.

Also, a lot of us in here dey talk with neither personal experience, nor background. More like those Tianshi, GNLD, FLP, etc marketers turned doctors wey fit swear on top their wares even when dem never see am in action before.



Also, I'm tempted to ask how the inverter could survive under regular rains entering it ? Abi make I no ask ? or mayBe na water-Resistant ?

Trippledots:



Hahaha....it is ok to ask. I myself don't know how it survived, frankly. I would come back from work and see dust mapped with water. So I assumed it was just splashes of rain, until the day I was at home and saw the whole thing. On a second though, maybe some fragile components have a coating to protect them from water splash but not being submerged. I dont know sha....the inverter still works.

bassdow:


if I were you, I wouldn't rest till I have had an understanding of HOW. it doesn't hurt to peep you know.

Would have said it's AirTight, but we know say being TRANSFORMERless, meant it contains lots of MOSFETs and Transistsors, etc and those would have HeatSinks. Even if na Transformer based sef, it still can't be airTight.

If na splashes, that's not much an issue BUT submerged, hmm I...

IYGEAL:


The depth of my well is within the same range as yours. I use 1.5HP. You might consider that as well if you don't use it for commercial purposes.

I had a similar problem with the old pump of same 1.5HP capacity. My cable is 2.5mm. It is not ideal but marginally better than yours, but the old pump was consuming about 2.3KWatts. I use a 5kw inverter too.

When the pump died, the new one (Astral) is significantly more energy efficient. It consumes about 1.6KW or so. Also, the power draw is stable.

When the old pump (I don't remember the brand) was in use, its power draw fluctuated (as seen on the inverter and BMS) a lot, ranging from 2000 to 2300 Watts. So I guess the excess power draw may come from your pump as well. That said, you also need to increase your wire cable size.

Please, can someone assist me in calculating the power consumption of my freezer. Thanks
