1. Yes, I want the stab to be in-between the nepa and the inverter(standalone felicity).

2. It's felicity 100A cc(FL-SCCM10048), voc 190, vdc 170.

Jefferyzz:
1. Yes. Ur inverter AC charge is 40a sheybi. That means a 3kva stab is recommended.
2. Yes. 3s2p will do

Penuelseun:
3kva stab will be too small for a 5kva inverter setup if you consider that the inverter has household loads on it while it will be charging the battery as well

@ stabilizer, it depends on the grid voltage supplied by phcn in your area, if above 180v a 5kva stabilizer wud suffice, if below 140v you need a 10/15kva central stab.

The above applies for a 48v inverter.
If yours is 24v, a 5kva inverter would serve ok even at 150v grid supply

Jefferyzz:
U dey use the inverter capacity judge the AC charger. Some hybrid 5kva av seen don't draw more than 40a to charge the battery. N that's 2kwh. 5kva will b a waste of cash.

dicksonadams:
hi guys, please I need the following used items, due to finance reason I can't buy new

used Charge Controller Mppt 20 to 30a
used solar panel
used inverter

my number on whatsap

08034288798pleaas

I beg

TechGeek777:


Thanks.

It's 50A I saw.

How does one calculate or determine the stab to use, is it 50A * battery voltage 48 Or 50 * Ac Voltage 220?

odimbannamdi:


If you still need this, holla.

I have one Powmr 60a MPPT CC i dont use aagain, but it still works. I also have 3 broken poly Jinko panels i am yet to install. I may consider selling one to you

earthrealm:


U forget to factor in grid voltage,
My mighty 15kva servo central stabilizer derates to abt 3kva if grid drops to 110v

dicksonadams:

hello chief i am interested, here is my number 08034288798pleaas, chat or call me. or drop a number let me call

Jefferyzz:
Maybe ur side sha. Nepa here dey pass 230v at times.

YOU miss the point...

are you giving advice to yourself or someone that lives in your hood?.

you should give advice that is al encompassing for possible scenarios the average user would encounter

With what lightening did to me recently, please disconnect

...1) An AGS (automatic gen start) powered off the Schneider 'XanBus' network will go offline in case of inverter failure or battery LVD - the inverter provides power to the XanBus network.

So imagine a situation where inverter goes off and Gen cannot be called to start because the device that is responsible to start the Gen is powered from inverter.

From experience, this has its drawback too though because, I have had Victron trip off on a phony overload error, and this happened at an odd hour and the inverters were not really being used..... Battery went down, Venus called for gen meanwhile the inverters were out. The gen ended up running for hours just wasting diesel till it was observed and the issue was resolved. I know that an alarm notification properly set up helps mitigate such anyways.



To your specific question, Victron throttling the Generator production in the presence of AC PV from the Fronius is a result of suboptimal settings or non kosher install.

On the GX device you must designate properly whether AC In 1 is Grid or Generator and ditto for AC In 2, you must also supply the inverter with power from Mains and Generator directly to each corresponding AC Input - the system will then start the Gen when needed and load/flog it correctly.

In the setup you described, there was probably a traditional ATS that switches Mains and Gen through a common output - we encounter this all the time in the field and either run out wires directly from the ATS to provide Mains and Gen separately to the inverter or employ a suitable contactor that switches the common ATS supply to Generator or Mains port of the inverter as appropriate.

The settings were actually done properly and all ACin inputs tagged appropriately in venus o, also cables supplying ACin 1 & ACin2 are direct from source no ATS in-between.. The dynamic reduction from the gen as Fronius harvest increased is actually a good feature as it helps to reduce diesel consumption overall. I just needed your explanation as to why that attenuation occurs.

Thanks boss for your inputs.

Whytehandy:
Good afternoon house, please I need a recommendation for a good 5KVA 24V smart hybrid inverter with low self-consumption (preferably wallmount type) with lithium charging capacity that I can use for my 1.5Hp inverter AC, fridge, freezer and other basic load like TV, fan and light.

A friend has already helped me to build a 230ah24V lithium battery bank and am also planning to buy at least 2400W solar panels.

I beg help me with the right choice of inverter as I am confused on what to go for. Thanks and God bless.

Lol. If he were home for that period, how would he manually prevent the lightning damage?

tunetokheyno:
Please I have a 1.5kva setup (2 wet cell battery and 1.5kva inverter) I am considering upgrading to solar, yet all the people I've spoken to are still quoting very high prices for me. I paid for my setup 260k last year and I don't want to spend too much, I need your advise.

My inverter manual (TV also) says disconnect from the wall in a storm.

I turn off the circuit breaker for the solar and AC charging when there's a storm.

NiyiOmoIyunade:


invest in sufficient lightning protection

litaninja:
@gadgetplanetng

This is where I was hoping we'd land

NiyiOmoIyunade:


Be aware that opening a PV breaker or any other breaker will not help protect against a surge, a decent surge will jump right across the space between the contacts and do its evil work. When a breaker trips upon impact from lightning induced surge, the surge current already passed through well before the breaker could respond.

NiyiOmoIyunade:
Indeed physically isolating a device from the wall socket or disconnecting the energy source should save it from lightning surge induced damage.

Be aware that opening a PV breaker or any other breaker will not help protect against a surge, a decent surge will jump right across the space between the contacts and do its evil work. When a breaker trips upon impact from lightning induced surge, the surge current already passed through well before the breaker could respond.

You either invest in sufficient lightning protection or physically totally disconnect the device e.g remove both PV cables from CC when a storm is impending

oloet:

Does this mean that surge can pass through a breaker even if it was switched off before a storm?
