Make sense. To solve the issues you highlighted, we could add an additional well sized breaker on the PV side on top of the double breaker. The double breaker protects the CC-battery circuit and also disconnect the PV side anytime d battery side trips while d low current breaker added for d PV side protects the PV-CC circuit...shikena

dmerciful,
you could avoid all these layers of complexity by just getting the right tool for the job.
a rightly sized midnite solar dc breaker for your pv and cc will give you peace of mind.
kiss (keep it simple and straightforward) should be our focus when it comes to renewables.
the money you save trying to cut corners could come back to haunt you when you
suddenly lose your precious equipment to fires or voltage spikes and you have to replace
them one after the other.

24v system. wired (1-3,2-4). I check voltage read with ordinary digital metre. I have not been able to use Cc to fully charge & go into equalization charge. I presumed one bat is lagging.

by rule I have never gone below 24.4v till day break before I shut down.
equalizing is rattling my brains

Obimind1:

I'll advice u separate those batteries, test them individually with ur digital metre to find out which of the battery is lagging. It will help protect other from running down over time.

efuro:


noted with thanks

Obimind1:

Congrats on ur newly purchased mppt 60 cc. How has the performance been so far?

DMerciful:
Oga I hail o. We are looking for low cost solutions. Kindly share this breaker u talked about

efuro:


honestly, mppt is superior to pwm.
I get info on my harvest& plenty info I don't really need too.
now I know I can expand pv gradually.
I have not really regreted my actions going AE/RE.
the first day i hit 1kilowatt "i said na me be dis?" even with my ye-ye 4 PVS.
for 2 months even NEPA has refused to bring bills too.
my dear oga obimind, how I which I had discovered this 2014 or even in 2015

dmerciful,

midnite solar dc breakers or disconnects are arguably the gold standard in solar pv breakers.
they may be a little expensive but over time you'll get better value for your money.
while there may be other cheaper alternatives which go by different names, its always better
to stick with tested brands which have proven themselves with time.
in renewables, we should be careful not to sacrifice quality on the alter of low cost
alternatives which do disappoint when needed most.

Hello all,
I need advice from the house.

I (regret that) I purchased a 12v tripplite inverter in 2014. I now want to go head on into solar.

I wish to power a load of 1.784kwh targeting 50% DOD for my batteries with 1 day autonomy. From my calculations, I'll need battery capacity of 297ah. I also calculated under ideal conditions, I'll need a cc of minimum of 59.5a and modules of 713.6w to juice up the batteries.

Estimated consumption: 1784wh
@50% DOD: 297.3ah (2 200ah batteries)
Hours of sunlight: 5
Min Charge controller size: 59.4a
Solar modules: 713.6w

In the future I plan to get a bigger inverter and more modules. By the time I get a bigger higher voltage inverter, will it be better to leave my present installation and let the new inverter power the remaining load? Considering that this is a small installation and how expensive MPPT cc is, should I go for an PWM CC instead of MPPT? I want an option that is scalable and cost effective.

I look forward to your candid advice. Help a brother not to make a costly mistake.

The installer said PWMs don't stress batteries like Mppts.

Dreamflyin:
Please, iwant to change my two 50amps PWM to mppts.
Each PWM is connected to a 1kw panel PV.
What amps should be better?
Also, how long will the four battery bank last?
