Yes, this type of SPD dissipates spikes and surge to ground. DC devices designed to mitigate intermittent voltage spikes in a pv system is different than a typical AC surge protection device. Here is an excerpt from LSP: SPDs are applied to electrical systems to provide a discharge path to earth to save those systems’ components from being exposed to the high-voltage transients caused by the direct or indirect effects of lightning or power system anomalies. ~~~~~~~~~~~~~~~~~~~~~~~~~ Does off-grid solar confuse you?

Surge protection devices do indeed work automatically but the still need to be inspected regularly. They degrade with use and if there have been spikes they give you that lovely automatic and transparent protection right up until the point when they don't and the next spike does something expensive to your upstream equipment! When the green flashes show red it's time to replace them.

As an electrician I would just like to add that this kind of hook up makes troubleshooting much more pleasant and efficient. No you don’t have to use this you can just splice together anywhere you want as long as it stays together, but when you have to troubleshoot a problem you will appreciate this splice box. Oh, don’t forget to label your wires, and be logical.

george, i am about to hook up 8 twelve volt batteries to a 24 volt panel system.8 24 volt panels. Do you think it would be ok to run them into the all in one lv2424 as sets of two batteries being supplied by two 24 volt panels instead of a set of 8 batteries connected in series and parallel as one big set of amperage from the full set to the full set of batteries. I was thinking my simpler method of sets of two 12 volt batteries and 2 panels may help isolate problems and make the battery system wiring user friendly for beginners (ME)

VOLTAGE = CURRENT X RESISTANCE This is the golden rule of electricity! It always applies. You can always solve for one unknown. There are specific reasons for hooking things up SERIES/PARALLEL. Wil Prouse Is extremely knowledgeable about PV systems, and you should buy his book if you don’t already have it. You will be limited by the equipment you have as to how to hook it up. The advantage I see on using the splice box is that you can isolate the circuit (whether it goes to the panel or the battery) by opening or closing a circuit breaker or fuse. This is not just convenient when you’re troubleshooting, but it’s a real safety benefit , when you’re doing routine maintenance. Whether you have 2 strings or 4 strings, you can isolate all the strings except the one you are testing. By doing this regularly and recording results, you will be able to detect problems early. If you have a bad connection or a Bad panel or battery, they will show up: REDUCED OUTPUT. If you can’t easily isolate the strings, you will have to manually break and make connections and test your results. I have worked in DATA CENTERS, which are extremely complicated. Try to keep your system SIMPLE. Over time, all systems degrade. If all your batteries and all your panels are the same brand/model and purchased at the same time, you should see similar degradation. Statistically the more batteries and panels you have, The higher the probability of problems or failure.

Blocking diodes. I'll have to research this more. Most late model panels already have them built in, yes? Isnt that standard/mandatory these days? So the diodes in the combiner boxes are an extra protection should the panel ones fail? Which would make sense. Is there a scenario where, if the panel diodes are in tact, theres still a chance of backflow, and the combiner box diodes prevent it? Again..I'll do more research, as I'm close to upgrading to 4 or 6 panels from just my single one right now.
@WillProwse
@WillProwse 3 жыл бұрын
Oh you are thinking of bypass diodes. Those exist in the junction boxes of the panel. Blocking diodes are different. They are in series configuration with the cells. Not parallel like bypass diodes. Bypass is for shading. Blocking is to prevent discharge of battery through panels. Most charge controllers have a feature that reduce the need for blocking diodes. I like them for using multiple arrays that are angled differently. That way one array won't bring down the other arrays if it is not angled the same. Great for step roofs with panels mounted on opposite sides.

Hi Will, I have a small setup, and only 2 x PV inputs at 13a each. My system is on a garden room, and ideally need about 3 x strings of only 3 to 5 x 430w panels. If I series them all together, the panels that might be in the shade (at different times) I believe would drag down the voltage of the ones actively producing. I can't parallel them as the amps would go too high. My question: If I used a combiner box like above would that allow me to kind of wire the panels up in series (but when a few are in shade) not drag the overall voltage down ?

Is there something like a combiner box that works in reverse, one PV voltage source in and multiple parallel sources out? Thought process here, i'm using all in one standalone solutions with their expandable batteries. So I have several areas that I could use PV to decrease grid reliance. If I could have the array go into a combiner and one cable carry that to a distribution system for the PV voltage that would make design easier.

I use 3 x 230W panels in parallel because in series the voltage is too high. Each panel is about 6A. Do I need any current protection? So far I used MCA splitters and that’s it.

Sorry if this is silly to ask but I'm doing my first solar setup for my office. I have a 24v hybrid solar inverter which can handle 55v to 450v and 6000w solar (over kill for my need). I plan to have four solar panels (430watts each total 1720) in parallel which from my research is better for me to do as I get shade on them sometimes (different panels different times of days / not all year mainly in the winter). Would this be over kill installing a combine box for my setup, what do people think?

Hello, I would value your input on this: I have 8 panels connected in series to my inverter (no combiner box), but I want to install another 4 panels facing the west to capture more sunlight after 5pm, how can I do that? Will the combiner box help me do this?

So the one question I never see answered on any videos or articles I've found on PV combiner boxes is whether or not inputs can come from solar arrays with different wattages. For instance an array of 100W panels and 200W panels. Cleary you do not want these tied together in series or parallel due to the power loss from the different wattages and people always talk about how you "never want to do this." Yet none of those same people mention a PV Combiner as a solution. What am I missing, as in my opinion I dont see any reason why a PV combiner box can't be used to join the outputs of different wattage panels yet nowhere have I found anyone talking about this as being a solution for just that.

Hi and thanks for another great video. As a newbie i have a question. I have a south facing array going into a one string inverter. However I am looking to add a small east facing array. The question is can I use a combiner to combine the 2 strings into the 1 string inverter? (it could take the capacity) or do i require another inverter? thanks

Not relevant to the combiner box shown, but curious what you'd use to combine eight separate 100 watt solar panels I'm installing on the roof of my Promaster van build. I see the Y connectors on line but seems to me the wire guage will be too small by the time I go through the roof to my disconnect/charge controller etc. Thinking of connecting all the separate cables feeding from the panels into one of those gray plastic gasketed electrical boxes located on my van roof and a single pair of heavy guage wires sized appropriately for the output amperage and the run. Any ideas for something better or simpler. Thankyou.
