Good day fam, please on budget, which maker of 60amps Mppt charge controller is recommended? Kindly give advice sirs

Maximizing Growatt inverter, putting as much as possible panels on it.

mctfopt:


Ok. Panels just arrived today. Growatt is on the way. Shipped from the US. WHEN it arrives I'll update.

Dam5reey:


Growatt was made in China, sent to the US then you bought from the US instead of China that is closer!
What's the catch?

So I checked on them Monday and explained my situation. But it isn't all good news jàre. Cos of the relationship we've had for a while, they know that my appliances are on solar, so if I complain of a faulty item, they know that it's most likely a factory defect and not due to misuse or NEPA surge. They've replaced for me before FOC a 32 inch TV on warranty within 2 years.

On the AC, they said they can't take it back cos it's been installed already. But they promised to help me get a buyer in no distant time. They said something however that caught my attention. That their AC sales (demands by customers) are mostly Hisense and that before they get to sell one unit LG, they've already cleared like 10 units Hisense ACs.



OMG! 1.5hp, and it's doing 900w peak. And that my own ńa just 1hp and even though the room is well cooled, I go dey hot for inside as I see am dey chop 1000w from my much coveted battery storage. Aswear, I don seriously miss road on top this one.

mctfopt:



Not recommended, but you can if you don't have a choice. Anyways when you do experiment of such nature, this may likely void the warranty on any of the product. As a DIYer, you sometimes just gotta do what you gotta do and damn what follows.

But if you'll love to do this, isn't it better to build your battery? I built my battery so I can do whatever I want.

Tax break. Green energy tax break. Lol

Quick question for all the gurus in the house...

I'm seriously looking at changing to lithium batteries. My challenge is the cost. I've also seen people advice that you can start small and add more later.

My questions are

1. Can multiple brands be coexist? for example, if i get a good deal on a 10kwh felicity battery today, and a deal on a 10kwh blue carbon tomorrow, can I add them?

2. can multiple power capacities coexist? say I can only afford 5kwh today, and tomorrow i'm able to buy 10 or 15kwh, can I add them together? or will I be stuck with 5kwh increments?

3. What's the maximum period between such additions? if I buy a lithium battery today, Can I add another maybe in a year or two? for tubular batteries, people usually say that it's not advisable.

Thank you.

I understand completely. My intention is to go with what people already have empirical evidences on, as it is tabled here for instance. So dual inverter it'll be. Or maybe even the newer dual inverter type B, as someone has mentioned here.

zeestone99:


It's sad that he got the wrong type of air conditioning unit. I too did not know LG makes different inverter ACs and energy saving is optional in some model.
I have a 1.5hp LG inverter ac that consumes about 400w plus after a while especially at night, I have seen it do 395w thereabout at some point. During the day it ramps up about 900w plus then drops to around 550w plus to 600w thereabout.

Drgreatone:

Update: So ended up getting a 2kva hybrid inverter early this year cos i needed my freezer powered which those ffl my story wud know. Still kept this inverter as back up and yesterday mistakenly put on the freezer on it and it powered it after a single beep. Turns out it was the fmr battery that cudnt carry my freezer. Now I av 2 inverters capable of carrying my freezer. Tempted to sell it but wit the way price of things are, its a good back up for my system.

kristien4:
How do you order from the US?

Xanderone:
So I don't wanna make another terrible error, this time with a central stabilizer. I may need to get one anytime as I was able to secure a prepaid meter that has for a while been installed but not used cos it had some error codes which made me unable to load a key change code and credit. The issue has been resolved. So I discovered the voltage supply is a terrible regular 160v and seldom 180v.

osayuwamwen:
Lighting killed my inverter and Felicity controller last night, am so pained

osayuwamwen:
The repairer has fixed the Felicity controller and he gave me 1kva inverter to be using first pending when he finished fixing my inverter, I have installed everything myself but I noticed this on my battery, the acid level on my battery gauge has gone down just for this few days I didn't charge the battery, I want to know if I can top up with distilled water at this level

Penuelseun:
Charge the battery fully first before topping it with distilled water

I did some searches and saw Prag, A&E dunamis models (10kva) and another funny name like this (Jor-El) 😁 as in Karl Kent name.

Anyways experienced users should kindly provide some info.

• Which models are tested and trusted? Few days ago, I pulled out about 4 units from storage that I last used about 6 years ago and realised they can't seem to handle the 160v input.

• How durable are these things? I read one of the reviews on Konga where a buyer cursed that the Jor-El he bought didn't last more than 6 months and it stopped working.

• How good are they in protecting appliances? My appliances have been safest on solar for many years now but foraging back into NEPA means I may be courting damage to these appliances from overvoltages, undervoltages and fluctuations.

• Any other questions that I may have missed but that experienced users know will also be welcome.

Thanks as always.

NB: I assume 10kva may suffice for loads which I anticipate may max to around 4kva with future upgrades/addition of appliances.

I also do not intend to hook my inverter AC charging unit to anything NEPA under any conditions whatsoever. It should continue to use the solar charging abeg, to avoid stories that touch.

I've however thought about installing an automatic rapid changeover switch to handle the change from inverter to NEPA whenever the latter gets the seizure brain waves to provide supply.

I will share with you my personal experience with these servo stabs.

THEY WORK AT THE BEGINING BUT WILL GRADUALLY FAIL.

Yes, they will fail because the movable parts on that huge toroidal coil will interact with the dusts that are settling on the spindle and coil. After a while, the dust might create a short circuit on the surface of the coil and then the stab will start dropping breaker or fuse due to the explosions from the short-circuit.
I have had this issue with more than four different brands, same issue ooo. Service center guys will try to file off the affected surface and it will work well only for the fault to return after a while.
I eventually stopped taking stuff to the service centers and started opening them up first damn the warrantee, see what went wrong and decide if I should go through the hassle of lifting heavy stabs to service center every now and then.
So during my quest, I discovered that DUST IS THE WORSE ENEMY OF A SERVO STAB.

Then I switched to a relay version and I have been using it for more than 5 years and counting without a single issue.

My Advice: If you must do a servo stab, make sure it's dust proof.

mctfopt:


Stavol by Matsunaga is a better make. Go to JiJidotng and search for Stavol AVR or Matsunaga. They do make awesome servo AVR

I saw a Bluegate 20kva there too, that stabilizer can boost 130v to 220v.

Thanks. Noted

Edited: The offers available on that website are all used o, both Stavos and Matsunaga.

I didn't come across a new one.

FEGEITOK:
How much would it cost to get a Lithium Ion or LifePO4 jumpstart package?

mctfopt:


New ones are available. Stavol is produced by Matsunaga.
