Hi! Have you ever heard of the Shoals Plug and Play cables / system? Can anyone judge whether it makes sense to use it? Although they seem to be a bit more expensive, they are extremely easy to use and no professional installer is required. Installation is also said to be very quick and more energy efficient than conventional cables... Some thoughts on it?

Instead of going to “inverter in” could you also go to the “charge controller”, then from the “charge controller” to “inverter in”?

Using this example, what is the voltage of each panel before series wiring? Also - what gauge wire would then be used on the output feed to the inverter?

Is there a type of "combiner box" available that can primarily utilize power from solar panels (when sunlight is available) and supplement its output with grid power (as a secondary source) only when the solar current is insufficient to meet the required output?

Why only the + cables go to Into the fuses when we have to use the + polarity and - polarity fuses in the junction box?

@MrPmanshimba 5 ай бұрын

I believe that the Fuse he is using are not 2 pole fuses so that's why.

@internationalbusiness5877 22 күн бұрын

What I learned today is that, 1 fuse is 15A and 6 panels parallel-connected to 1 strings is equivalent to 8A x 6 = 48A. Which will overload the fuse and blow if we connect it like your diagram shows.

I think there series strings coming in so only 8-11 amps per string.

Can you explain to me why you connect all the (-) and (+) ,except the first (+), together and then conect them with a black (-) cable to the combiner box and in the meantime draw a red (+) cable of the first (+). Instead of connecting separately all the (-) of the panels together and connect them with a black (-) cable to the combiner box and all the (+) together and connect them tο the combiner box with a red (+) solar cable?

• All pv strings connected in series The series circuit definition states that a series circuit is a path where the current flows from one component to another through a single path. • In these types of series circuits, the negative terminal of the component is connected with the positive terminal and vice versa.

@sale666 9 ай бұрын

This is a series connection looking at the panels... the only thing that makes it parallel is the bus bur.. you should than connect each string to its own fuse and than from the fuse to its own breaker per string... assuming your inverter handles 4 separate strings in

In the series string, solar panels voltage is added, and the current remains the same. In parallel string connection, solar panels voltage remaining the same, and current adding this depends on your system

In this scene in the video, the current and voltage of each string should be consistent.

@mosfet500 Жыл бұрын

Won't work, series voltage is too high for charge controllers in off grid apps. Running long strings is best with microinverters or SolarEdge optimizers in intertie apps.

@charliewatts6895 Жыл бұрын

Agree. Assuming each panel is 25 volts VDC (conservatively), that's 150 volts per string x 4, or 600 volts. That's packing a wallop, and well above any controller (Just the first string along would exceed capability for my off-grid controller). For safety reasons, it's not recommended that 100 volts VDC be exceeded. VDC at the level can kill.

I have solar panels that are rated 540w My vmpp is 40.5 v I’m aiming to connect them to an inverter that runs a motor for water pumping I will use 64 panels so they can provide 34kw. So I’m using 4 strings each with 16 panels in series If i add up the volts in one string i will end up with 650dcv is that dangerous? Also what do you suggest?

@mosfet500 Жыл бұрын

@@user-xb2of4sr9q According to what you are saying each of your modules puts out 64/34k = 531.3 watts. I think there might be something wrong in your calculations. Microinverters, that is an inverter on each module, run high voltages as the string voltage is the sum of each module. If you're are feeding an inverter or charger controller that runs low voltages you have to make your bank something like 2 modules in series connect in parallel, that is 2 S x 16p, that will give your a total voltage of~81V .according to your VMPP of 40.5 V.
