I have a question for gurus only. is there anyway I can configure 2 separate pv stream on a single 300v DC mnspd. i could not get 115v dc type when I was buying and I had to buy the 300v because any form protection is better than non even though most cc protection is not up to 300v except TriStar

in as much as this question was dedicated to the gurus only, nevertheless let me try small...

if there are 2 separate PV streams, that means you have 2 separate PV arrays. having 2 separate PV arrays means you have 2 separate SCCs; one for each of the PV array.

MNSPDs are usually connected to the upstream of the SCC. so I don't think you can configure "2 separate streams" on one mnspd. if you do that, you've effectively paralleled the 2 PV streams to the mnspds which means you have to use one SCC.

NB: if you're using 2 separate PV arrays, it means that either the 2 streams contain PV modules that are not closely matched together or the 2 streams are on a separate orientation (maybe one is facing west and the other facing east... which is my case). both of these scenarios requires that you use separate SCCs for each of the array; and in both case, the individual SCC should have its own mnspd.
another case might be that both arrays combined together will be larger than the maximum power input of one single SCC

SUMMARY: 2 " separate streams" requires 2 separate SCCs which requires separate mnspds

As always, the above is strictly my personal opinion. if I'm wrong, correct with brotherly love and not critics.
Cheers

over to the gurus...

I agree with you fully.

Each separate PV array must have its own CC and if you must protect the CCs with an SPD, each CC must have its own SPD.

Any attempt to combine two separate PV arrays to one CC or SPD is very likely asking for trouble especially if the combined PV ampacity exceeds the CC limits or the array voltages are dissimilar.

The magic smoke would come out pretty quick in these scenarios.

An SPD is desirable and very good to have but not compulsory - if you can afford only one for now, simply dedicate it to the side of the installation that is most precious to you while you save up for the second SPD

House pls help

godspeed:
Hello

Kiekie and other vendors in the house.

Pls can I get an electric charger for my tubular battery, 12 volts and preferably 20amps.

Pls note it's not a solar charge controller that I'm requesting for.

The charger on my inverter seems to be faulty

@McTrinity, @ Niyiomolyunade

thanks for your honest views.

I know cc don't like sharing input arrays. I thought our nija spirit has created a suitable work around as expected.

I will have to pray hard then.

godspeed:

House pls help

sure, you get get a standalone smart charger to charge your batteries, contact kiekie and the other sellers, or you can buy from konga or jumia. i got a smart digital 3 stage 20amps charger, that automatically cuts off charging when batt is full off konga

efuro:


if your company failed me I would have stated otherwise.

you're welcome sir

if he has a magnum e-panel he could actually use one mnspd on all his arrays regardless of the size.

Nice one Oga GeorgeD. I never knew that was even possible to do.

The e-panels I saw cost about the price of 4 Midnite SPDs sha. Will still do more research on it though.

If one could find out the working principle, one might rig something similar up at much lesser expense.

I got 2 low power ceiling fan from Juo about 4 days ago and I am been really impressed by their performance. The lowest speed for the fan is about 5w (I checked with my battery monitor) and the max speed (which is faster than any ceiling fan has any right to be) is 40w. At a speed level of 1 to 5 I often find 2 to be sufficient for all needs. 3 4 and 5 are just too insane for me. Speed two is about 10w. I did a video comparison with a conventional fan which I will share with a proper review very soon

Does Oga JUO have a standing fan variant of this device?

Did you need a DC DC buck converter to reduce the dc voltage to 12V?

Ativ:


Did you need a DC DC buck converter to reduce the dc voltage to 12V?

It came with an AC to DC converter, you might need a buck converter if you intend to use it with relatively high voltage DC

if the CC and inverter allow you can ground one leg of both the arrays and use one MSNPD to reduce the risk by 50 % or more

mcTrinity:

the 2 streams are on a separate orientation (maybe one is facing west and the other facing east

What if one uses a diode to ensure that east facing array doesn't flow into west and vice versa, will one still need 2 CC

mank1234:

What if one uses a diode to ensure that east facing array doesn't flow into west and vice versa, will one still need 2 CC

Yes, you will need 2 CC as maximum power point will vary for arrays facing different directions due to different insolation.

Even in a single array, MPP varies amongst panels, not to mention different arrays.

Goodmorning house please how long does it take for battery balancers to sync the battery voltages?

DUNKA:
Goodmorning house please how long does it take for battery balancers to sync the battery voltages?

Not even a week, I can tell.
Except for brand new batteries where balancers were added at first run, then it happens faster.
