Calculate Solar Panel Cost For Your Home - www.solarreviews.com/solar-es...
Understanding the basic components of a grid-tied solar system will help you when selecting the right system for your home and monitoring/maintaining your system during the multiple decades of operation. I will provide an overview of a PV combiner box using an Enphase IQ Comber 4 which was recently installed on my home as part of an 11.3 kW system.

So awesome to see our work on your channel! Looks clean and I’m happy you’re happy with your install!

Yeah buddy, thanks for the help Julian 👍

Solar is Fun! I got portable panels, a solar generator and my big 10.3kw roof top system.

@everydaysolar 7 месяцев назад

What brand did you go with for your solar generator?

@gregpochet4812 7 месяцев назад

@@everydaysolar All Powers for both(Panels and generator). I wouldn't recommend them. My 1st generator stopped charging from all sources in less than 3 months. Its a 300wh one. They sent me a new one. The panels were rated at 140w, was getting max of 50kw on the clearest, brightest sunny day in Summer. They also sent me a new one. That was a good deal for me as I now have 2 panels and connected them via parallel , which I learned how to do from YOUR videos..

Ran into this seeking info since my IQ Combiner 3 PCB failed. They sent me a replacement. But solar company wants $250 just to show up. Nice info.

@disneymike3311 20 дней назад

Great video! Can you make a video about the output of the combiner box to your main panel?

@jayfitzgerald6074 7 месяцев назад

Thanks for getting me started with my system. I would recommend that you don't poke around and electric panel with a pencil, the graphite center is a conductor. I would like you around to see more of your videos.

Enphase tells you how many micro inverters you can string together, but others don’t. I’m specifically looking at Aptos, and I can’t find anywhere where they say what the maximum number of inverters you can string together is. Am I missing something? Could I just string together 30 Aptos micro inverters and skip the combiner box? Thanks

@skyweb6560 5 дней назад

I haven't been able to find any information online or enchase forum to see if I can add an existing string inverter with 30A breaker to Combiner 5. The new combiner 5 im adding will have 1 60A feed in from a QAgreggator only populated with 2 20A branches so Total input into the Combiner will be 70A well below the supported limited. Im hoping I can run my new i8+ branch and the old inverter system through this combiner, and the production CT. I don't think it will mess it up? Any Thoughts?

@hank-kal 7 месяцев назад

Thanks for the detailed info, very helpful! Regarding the line losses of the AC power coming from the mircoinverters into the combiner box - is there less line losses over these wires because of the fact that this is AC and not DC power, like with a DC power optimizers approach sending DC power over these lines to a string inverter approach, or are these line losses exactly the same regardless if they are sending AC or DC power down from the roof along the same length and type of wires?

@everydaysolar 7 месяцев назад

Line loss is proportional to the current running through the wires and independent of whether that is AC or DC. With this in mind usually micro inverters (switching to AC) will help to keep your wire gauge lower as the current will be much lower.

@sergiopadilla8716 4 дня назад

It looks like they wired your 15A breaker in the combiner box incorrectly.

@LarryRichelli 4 месяца назад

I can't seem to get this question answered. In a seven K system I am thinking of buying they are using 18 400 watt panels with Enphase 8+ micro inverts and because I want to add a large EG4 PowerPro WallMount AllWeather Lithium Battery | 48V 280Ah | 14.3kWh LiFePO4. They are telling me that they can hook this battery up to my system included in the the cost. This will be a grid tie system so any chance you can tell me how one would connect a DC battery to this Enphase system and make it work. Thanks for any help you can off because I don't want to sign a contract and then not get my battery connected. Thanks again.

@SXMaarten01 5 месяцев назад

I live in the Philippines'. The grid has no zero lead. Just 2 127V leads making 240V. How do I connect a combiner box with 2 fases.

@mustaprox 7 месяцев назад

Thanks for the info. One question, is the combiner box responsible for detecting any reduction in power in the case of partial shading and/or panel failure? or is that the job of a regulator further down the line?

@everydaysolar 7 месяцев назад

Good question, when it comes to minimizing the impact of shading on 1 or 2 panels across your entire array that would be handled at the micro inverter. This is one of the benefits of micro inverters even though string inverters often leverage "power optimizers" to do something similar.

@Superiorsolarconsulting 7 месяцев назад

The micros communicate with the envoy which is inside the combiner box and then the envoy talks to your wifi. You can see it all in the enlighten app

@theweldingmachine 7 месяцев назад

quick question I have a 200 amp meter combo panel that has 4 spaces, that are all full but 1. Can I run a 200amp sub panel off of that? I'm trying to run another 100 amp sub to a shop off of the 200 amp sub(welding shop) is this possible. Thanks for the videos.

@everydaysolar 7 месяцев назад

You just have 1 open space? So can’t even fit a double pull 240V breaker ( 2 spaces)?

@theweldingmachine 7 месяцев назад

@@everydaysolar could i transfer the other breaker to a sub panel next to it with more space

@user-lc1vg9pr6d 7 месяцев назад

What is the best way to upgrade a Solar edge system I’m not outputting enough and need about ten more panels

@everydaysolar 7 месяцев назад

In that case I would probably stick with a string inverter. What size Solar Edge do you have now? Might also look how you are feeding power into your main panel. If you are going into a breaker on your bus bar you might be already at the max breaker size for the size of panel. You have to follow the "120% rule" called out by NEC. In a standard 200 Amp breaker that would be 40 Amps. Little hard to know all the different factors to consider and you could jump over to our Everyday Solar Facebook Group if you want to dive deeper.

I just got a quote for $30k for a 16kW system. No batteries and will consist of 38 415w Bluesun panels with apsystems microinverters. Do you think that's a fair price?

@everydaysolar 2 часа назад

The pricing is very competitive per watt. Almost too good to be honest. I paid over $3/watt and you are at less than $2/watt. I have a DIY installation coming up and it will still be $2/watt just for the equipment (Tier 1). I don't have any experience with Bluesun and Ap Systems but definitely not as common as REC, QCell, Trina, etc. and Enphase for the microinverters.

@RedBatteryHead 7 месяцев назад

That's a huge price on that install.😮 So the input is already from an external inverter. So 3 externals?

@everydaysolar 7 месяцев назад

Nope, we are using Ephase iQ8M micro inverters. So the output from each of the micro inverters in 240V in series consisting of 9 on 2 of the circuits and 10 on the 3rd circuit for a total on 28 panels/micro inverters. Hope that makes sense 👍

@RedBatteryHead 7 месяцев назад

@@everydaysolar is that more efficient than larger inverters?

@RoyalEnfielderKtm 7 месяцев назад

@@everydaysolar "the micro inverters in 240V in series ", Please correct me if I am wrong. The IQ8M are in series, but the 240V from those MicroInverter are in parallel (to keep voltage at 240V). Each string produce 240V, combined in the combiner box. I assume you have a 120 / 240V "split phase" residential feed thus only 1 phase. (the usual residential feed in the USA, unless you have 3 phases.) Thus at 3:10 you have 2 lines (L1-red, L2-black, N- white). Not 2 phases. Ground is green 240 V between the L1 and L2. 120 V between L1 and N. or L2 and N (the IQ-Gateway board is connected to 120V)
