In addition to what Niyi has said, add a Time delay switch to delay load transfer to the generator. You don't want the contactor and by extension the loads to chatter during manual Gen startup.

Trippledots:
I'm already playing with an idea in my head for the other relay. Whereby my manual start generator excites a second relay that transfers the load to the gen from grid. when the gen is put off it returns to mains. That way i dont have to always use a knife switch to switch between grid and generator manually.

Good afternoon everyone! Please I want to know if 10kva inverter can handle 10hp 3 phas borehole considering the surge capacity and which type of the inverter is good for the job? Thank you!

In my own POV, i'd say NO
HOW;
A 10Hp is approx. 7500Watts ...
now a 10KVA is also .. 8000Watts i.e. if by a power factor of 0.8 ....
putting into consideration a 2 or 3x surge .... i'd say it's an idea DOA .... personally i dont think it can work but i be small pikin for solar inverter world ... i'd love if my "Oga at the top, talk for the matter". Thanks
also in addition its a 3- phase ... most inverters i know of are in single phase.

I greet my great people in the house....

I just launched and installed a hybrid Must PV1800 VHM 24v 80A MPPT inverter with Wifi RTU (remote monitoring) to relief my giant Bluegate 2kva inverter after serving tirelessly for 7years without a break and my Itracer 60A MPPT charge controller.
i resulted to this when i couldn't figure out remote monitoring on my itracer with Raspi.
Presently i have moved my 2400w panels on Must inverter to see how it works...
i noticed the inverter doesn't display SOC/DOD, data log unlike Itracer.
i will give more review as times goes on.

Chai, and i saw one analogue timer oh. I just overlooked it. I'm sure it wasn't more than #500

NiyiOmoIyunade:
Interesting idea. The possibilities are truly endless if you put your mind to it.

For the mentioned application though, I would be happier if you used a suitably rated contactor instead of a relay, granted your loads are small but I just prefer a sturdy device for switching and you would also need to isolate the loads the contactor will switch e.g you don't want your small Gen to try to power up the AC or Microwave or Freezer or other high wattage appliance when the mains supply fails.

See below a picture of contactor vs relay - see how small the relay contacts and internals are - hard to get thick wires into the relay and their mechanism of failure is also more a bit more spectacular.

Safety is very important above all else and we don't pray for any mishaps - for this reason, I have a bagful of relays I will no longer use since my needs are medium to heavy duty - free giveaway as well for anyone who can pickup who wants to use them for very light duty applications.

Now I am looking for that 80A relay Oga Dapsyra mentioned to play around with Source anyone

Your concerns are well noted, sir. I am pretty confident of my loads and the relay rating.

@free relays.... I wish i was near you oh. I laik osho free.

@source... Arena at oshodi is a harbinger of all sorts. I saw a 3P 2T relay of 80amps the last time i went there. If that what you need i can direct you to the shop. I collected the seller's business card.

I think I am just paranoid and extremely safety conscious sha!

You definitely know what you are doing and are capable of assessing and mitigating any risks.

I will reach out to you to discuss all our outstanding matters.

Ok... Thanks so much. Really appreciate you.

I would say it is desirable to add a suitably rated circuit breaker between a charge controller and battery for two reasons;

1) To comply with code requiremements
2) Electrical safety in the event of an overload or shortcircuit condition to protect the wiring and prevent a fire

Personally, I don't use a circuit breaker though, I use only a manual disconnect because of my experience with a nuisance trip that destroyed my charge controller way back. I also trust the inbuilt current limiting features of a premium CC - once I have installed using the right cable gauge - slightly oversized for some fault tolerance

Barezzi:
Evening guys,

This one is a tough question that leaves every1 to his own opinion. Personally I don't like d idea of using breakers in btw cc n Ba3... If the breaker trips cc gets fried, and the only thing that can mk it trip is if there is short circuit on the ba3, that ll nt happen if the ba3 terminals r well covered...

But If the wrong hand go trip dt breaker n cc fry, e go pain person o, i rather leave it abeg

My sentiments exactly!

It depends on the cc. In any case I recommend using one or a battery disconnect switch. And manufacturers too recommend it. You can use one that disconnects bot the solar and battery uf battery were to trip.

1) some Cc can handle situations where battery mcb trip but solar is still on. Previous Morningstar firmware version wasn't able to handle this but it seems later version solved it. Axpert, Victron and Epsolar handles this conveniently
2) if you're a Morningstar user, when u want to upgrade firmware, you'll need to break the connection btw cc and battery at some point.

As adviced, you can use a breaker that disconnects solar and battery together. I think its the safest approach.

this is where I stand. cost/benefit/safety analysis. size/oversize ur link cable, protect/cover terminals Wella, then leave cc to do it's work

It is not necessary. It is mandatory! While I'd rather not have a breaker, a once-in-a-lifetime experience showed me how necessary they are. As always, the breaker is meant to protect the cabling from combustion. In essence, you are required to use cabling that won't jeopardize your installation i.e. large enough for max loading (with some headroom) yet not so large that your breaker would be sized to allow Nigeria to burn down before it trips, if ever.

If I try the double breaker thing, because of the enormous rating mismatch, my PV would never trip off under any kind of fault.

NiyiOmoIyunade:
Lol My Oga. The sages say necessity is the mother of invention

You got a much larger contactor than I use - 80A 2NO 2NC to my own 40A so it makes sense that you paid more.

What I find though is you get better prices as you move closer to the source so my first ever set of LC1D25008, I got at 20k for two units including delivery to Lekki, same contactor I got now for 3k each as I cut out the middle man and moved closer to the mainland source - if you factor logistics they came at 4k each now.

Interestingly, I just took delivery of a batch of stuff from Ali... 25A Tomzn 2NO 2NC contactors and each cost under $6 - after my trials, they will now be my electrical switch of choice for large single load or multiple small load switching applications for my clients, the prices were so good I got a few random stuff as well - several large capacity AVS and diverse DC breakers - with a few hacks taught to me behind the scenes by a member of this forum, I got the entire package to land at my doorstep in a little over 1 week at a great price.

Your comment about duplicating dual AC source and output just sparked off a few ideas in my head, I will experiment and revert if I succeed - I may yet make my own Victron clone afterall.

I need to replicate your one-week-delivery stint. Kindly chat me up when free.

mcTrinity:


well, inverter inefficiency and/or battery ineffectiveness has been pointed out.

however, my small little personal observation is just the design. 3000W PV array on just 200Ah Battery Bank
that's about 62A (3000W/48V) hitting the battery during bulk charging. unless you're running freezers and ACs during the day.... which is even unlikely since it's just one bank.

I actually have a similar PV:battery bank ratio. Yes, I run two deep freezers and a fridge on mine during the day, asides other stuff like washing machines. The CC should handle the max current deliverable with ease. Mine is a Midnite coupled with a WizBang Jr.
For fear of overhyping the combo, you can limit charge current and determine end-amps (charging no longer terminated by time lapse).

Night-time loads peak around 200W and average about 150W (some LED lights of 3W - 5W, a 47" LED LG TV around 35W, an occasional 32" TV during football season/holidays and 2 ceiling fans of 25W). At bedtime, TVs and most lights go off, an extra fan or two might come on so loads stay roughly the same. Security lights are automated DC and powered by a different bank/PV array. Night-time inverter is 48V 375VA and has a self-consumption of 9W.
The key is in minimizing consumption. Currently eyeing JUO's DC fans for an even more efficient system.

Anyway, no well-meaning SCC should kill batteries simply because you're overcompensated on PV array size.
