I am looking to power a 400 watt power inverter direct off solar If I wire 4 units in parallel and set the volt to 14 will there be a problem

There are two variables you have to answer first, 1. Can the solar cell provide the amperage nescessary?2. This is a non isolated step down meaning voltage output is lower than input, and there is no isolation between the input voltage and the output voltage, Are these conditions conteplated in your calculations first? If so then it may work....

In theory im sure you could. However each unit waivers at different loads so it will be near impossible to synch up the voltages perfectly. Modifying the heatsinks, you can actually push 200Watts through each unit. If you need to convert more power I would recommend buying a larger unit.

NO! Don't put them in parallel. Because they are not identical, one will have a slightly higher output than another so it will attempt to supply more than its rated 100 Watts. Eventually it will fail. There's no way you can interconnect them to obtain equalized load.sharing.

One 85 watt panel Should deliver around 7 amps at 12 volts in full sun. If you have all 4 panels connected through a single (7 amp) controller, it is way overloaded. Sounds like you might need 3 more controllers or simply a bigger controller unit.

NO each controller can only handle 12 volt x 30 amp or 360 wattyour 4 panels will put out 580 watt If you use it in a 24 volt system it can handle 720 watts but it has a max input of 30 voltsso 2 controllers for your setup or get a higher amp controller if you plan to add

From my experience I have a 500 watt sun gridtie inverter and a 600 watt sun gridtie inverter with 4 250 watt grape solar panels connected in parallel everything is good runs warm but I keep a small fan on them I would say no more than 500 watts on that 600 watt inverter.

Michelle your would have to look at the watts on the AC unit. ? And I could give u better answer This inverter is really a great unit but keep in mind battery. I tested it out and run a portable ac for 5 minutes on 1 fully charge battery. It worked great. My battery bank at the moment has 4 batterys links to solar panels AC unit would upto 30 minutes on what I have. Hope that helps you Inverter great. But you need a lot of batteries to run power drain units like AC Units

Yes, #4 will easily handle a 500W inverter. You could use smaller, 6 or even 8 if you keep the length short. I have this kit on my 1500 watt inverter.

Hi Aimee,Thank you for your inquiry! This system by itself would not be able to generate 4Kw / 4,000 watts per day because it is only a 1.2KW / 1,200 watts system. There is not enough battery power and solar power to sustain 4Kw, plus, the inverter is probably not large enough to sustain multiple devices at a time. It can probably power certain devices in your home, however, we would need the specifications, including the watts and running times, for those devices to determine that information for you. Please let us know if you have any additional questions.Best regards,Earthtech Products Hi Aimee,Thank you for your inquiry!

Yes, I use that size panel too, inverter works good. Any panel voltage should not exceed 60 volts, watts should be well under 600 watts, so no more than 2 of those panels

I have five 100 watt panels now, wired together with MC4 split connectors and running 25 feet to my charge controller. My panels have a working voltage of 18.5V. That gives me 5.5 amp per panel in direct sun. In total I get 27 - 28 amps on a clear day. I have no problem with voltage drop but I am now max'd out on my 30 amp charge controller and the 10 guage wire. If you have a larger system than that you will need heavier wire, unless your panels operate at a higher voltage, wich would lower your amps. As long as you are under 30 amp this wire works great. I hope this helps.Dan

No Way. the peak load for an AC unit is probably (3) times the running load (which already exceeds the 500 watt rating of the inverter).

Don't know? Mine is a 400 watt and I have had no power problems, seems totally sufficient to do the job.

I have not tried loading the inverter at its full 600W, but have connected one intended for 12V panels (I think expecting 10 to 30 volts) to a 24 volt system battery... which ran it very fast and hot, but it complained and shut down when the voltage got too much for it, cooling off and ran again. Unless you do have cold and very sunny conditions, the peak loading is never for very long, and I have never had the full output from them. I'm surprised to see other reviewers with bad experiences. I would believe the protection circuits they use.

Yes, the Inverter should hook directly to the battery, with very large cables. You can run your low wattage dc loads off the Renogy 30 amp charge controller. I run some 12 volt dc lamps off the charge controller. See the diagram on Renogy's web site for an example... Follow the hookup order for the cables to the charge controller

Yes, most solar panels can wire up directly. But my recommendation is go with 500 or 1000 watt grid tie inverter. The 250 will burn out quickly.
1505814
Yes, you can do that. Bryan has provided a good answer to this question. Also, since the panels are 12v, you are limited to the grid-tie inverter selection. You'll probably need a low voltage, high current grid-tie inverter, yet this may not be UL listed.

From My experience the "30 amp" Sunforce controller is not robust enough for the output of the 4 158 Watt panels. I had to buy an Outback controller. Because there does not seem to be a good inexpensive controller in the realm of 30 to 60 amps out there. You could get 2 controllers and split the panels. A little more info on the Sunforce controller, they die quietly for the most part, and there are some Websites out there that may have figured out a way to beef up the controller. The world of solar is very seductive and can suck your wallet dry in minutes... or months. If you are just trying to supplement your home use, and do not need power at night, you should consider getting a 500 watt grid tie inverter. During the day the inverter will produce power, and run reduce the speed of the electric meter, if it makes more than you are using it will run the meter backwards.They plug right into the house, and they have island protection, meaning that if the power goes out the inverter stop. Amazon has them,

Yes if you have solar panels that put out as much as 32 amps controller. 12v x 32a =390 watt. This is a pretty big system.
