Do I need to buy more stuff?

[Skooliemom]

Ok so got some questions.

I have 4-250w panels see photo. Planned to be wired in series and parallel.
renogy 30 amp charge controller to the batteries.
2 - 200 amp hour AGMs Renogy. (Series?)
fuse150 amp (not sure size???)
then that will run to an inverter (MSW) 1,000w
A fuse block I use A LOT OF 12v (usb) stuff the inverter is just for the TV.
Also got this Alitove DC 12v 20a 240w Power Supply Transformer Switch.

I do carry a 2000w generator

Assuming 24V battery/inverter.

1000W/24V = 41.7A - your 30A controller (assuming MPPT) won't capture all your solar. You need 40A.

MSW inverters are generally more inefficient than PSW. If all you're running is a TV, then I would consider getting the smallest PSW inverter possible. Inverters themselves consume power. Bigger inverters pull more power just by being on even when no loads are applied. Here's a 500W:

Not sure what the purpose is for the 12V/20A power supply.

Not entirely sure what you're looking for without knowing your goals.

One thing that stands out is 1000w of solar and a 30a PWM charge controller.

And assuming 12.8v system (or missing 24v to 12v converter):

1000w / 12.8v = 78a of charging power
Which is nearly 1/3 as bug as it could/should be.

Schoolies (schoolers?) tend to want to just build something and live with what they got rather than plan for needs. (Its early, and i am on my first cup of coffee and apparently judgey today! )

Power supply is for?

I ordered a 40 amp mppt CC today. The inverter won’t be used much so not really worried about it. 12v powers everything lights, refrigerator, phones, tablets, security system, WiFi router, a mixer(yes,12v)

 

[Skooliemom]

I have been in my bus for almost 2 years. I only had 1-250w solar panel and the 400amp hours in batteries it was not getting full. So I needed more panels. I got a heck of a deal. So I got 4. I have added a picture of the charge controller for you it says 12/24V

no converter but can get one do you have a recommendation?

goals just to make sure my 12v items are powered all the time I honestly don’t need an inverter but have one just because.

Probably a good thing. Make sure you configure your array to falling the MPPT range of your MPPT SCC.
This "may" mean putting panels in 2S2P arrangement but that mostly depends on the panel Voc (found it: 37v) and SCC input requirements.

If you share your SCC input info we can help you set it up to operate most efficiently.

This is what I have now 30 but I ordered the 40. I planned on running the panels in 2S&2P setup. Could you help with the correct connectors. I know what it should be but when I look I get confused lol

Is your battery configured as 12V or 24V?

 

[Skooliemom]

Nothing is done to them yet. I have 2 of them.

 

[MisterSandals]

Could you help with the correct connectors.

What connectors are on your panels? MC4?
You will need a Y connector to join your 2 series panels so using the same type Y connector is easiest.

Here are MC4 connectors if that is what your panels have

Yes I get that but are you going to connect the 2 batteries as 12V or 24V?

 

[Skooliemom]

Great got them order

 

[MisterSandals]

Great got them order

You realize you need to have connecting MC4 pieces to make your lines to the SCC right?

This will get you 10'. They come in different lengths, premade which is handy and a little spendy.

Ok you lost me. I have 1 set of MC4 wire with connectors. In photo below I order 1 set of the Y connectors you listed.

I did not see those in your pile of stuff...

That is what you need. Will it be long enough to reach the SCC?

Yes.

I HIGHLY recommend getting the Bluetooth model (adds BT-1 module?). BT is REALLY nice to have. I know its $25 but this is really a well spent $25. Trust me (and everybody else who has one!)

 

[Skooliemom]

ok, no big deal anything else I need to buy lol

 

[Skooliemom]

Was thinking 12v

 

[Forbisher]

Was thinking 12v

Ok but you are buying a 40A SCC which at 12V x 40A is only 480watts panels.
but you have 1000watts panels that will require an 80A SCC. 80A x 12V is 960 watts.
Charge rate of your AGM battery has to be considered too.
