how many amps per panel
1856501
The number of amps per panel depends on the the amount of light on the panel. At the rated maximum 130 Watts, (Watts = Volts X Amps) so, about 10.83 Amps per panel maximum at 12 volts. Don't expect the maximum, that is in nearly perfect conditions and location. I routinely get about 15 Amps to the battery at noon in the summer in Northern California.

Each panel is 130 watts and 17.1 volts output and 7.6 Amps. 17.1 x 7.6 = 130 When I connect thur a solar charger on a sunny day it can read into a battery 13 volts x 20 amps = 260 watts input to the battery charger

only around 8 but I don't actually realize that many. I don't have the opimum agial to get what I should and it is winter time when the sun is not as good a source. I have not mesured the answere either. So I am not getting more then about 3 at most times right now.

Amps=watts/volts. So 250w/24v=10.4 amps. This is considering full output of the solar panel and no loss through cabling. So to be safe you can run three solar panels More than likely you can get away with four, as you will likely never see a full 10 amps output.

these batteries should be charged at 35 amps or less, 15 amps is optimal. A single 100 watt panel is fine as it will charge at 8 amps max.

4 panels is approximately 32 apps there is a lot of variables like temperature size of your wire and proper angle to the sun under perfect condition you could see high of 36 Amps ! I would not recommend your charge controller for 4 panels . 30 amp charge controller is typically good for about 15 A continuous .

Hi, For this panel a 10 Amp Controller will work and be expandable up to 100W at 12V. Thanks, Renogy TO

I would, 2000 watts @ 12 volts = 166.6 amps. The hot leg of any circuit (AC or DC) should always be protected with a fuse or circuit breaker. If you don't have a manual on your inverter search the internet to try to find its spec sheet to find out its max load in amps then size your fuse (or breaker) just slightly larger then it's max amp load

How many watts are the panels? This wire is a small gauge so if your panels are over 40 watts and capable of generating over 2 amps you are going to need heavier gauge wire. I have 160 watt panels capable of almost 10 amps and for 30 feet I am using the Zamp extension cable which is 10 gauge. There are tables available on the internet to indicate the gauge required for various currents and lengths at 12 v.

70w x 2 at 110 volts? Amps = watts/volts. Amps needed 140/110 x 24 hours =30 amps in 24 hrs. A Renogy Starter kit of 3 panels puts out 300 watts, roughly 1500 watts, or 13.6 amps daily. So 9 panels? Ask Renogy. Also need batteries (golf cart batteries are great) and inverter.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

A 30A Charge controller WILL be adequate and will work but it is a narrow margin for your 145 watt panels. I estimated the amperage on your panels @ 7.25 amps each, that put you right at 29 amps. Barring any solar fluxes that might tip the controller to temp shut down you should be ok.

The maximum voltage that these panels, in series, can get up to is roughly around 45 volts. So any voltage meter/monitor that you get should be able sustain at least that much voltage.Thank you,AW

This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max. But I find mine realistically charges about 5 amp hrs per hr. So 210ah/5amp is 42hrs of charge time. so you prob have 7-9 hrs in day of good charge, so 42/~8 is at minimal 4 panels... I live in midwest and have less sunlight per day. But I think 4 is about minimal. I work more with electrical consumption than I do with battery charging so someone else might have better charging math, but I am familiar with electrical systems. Hope this helps and sorry for all the math, just wanted to back my answer. Good luck.

Theoretically, in ideal sun conditions, your max amp output would be 40A. The adapter would parallel those 4 individual 10A panels together, but it would be up to your charge controller to determine the actual voltage and amperage supplied to the batteries and act as the brain and prevent overcharge.

The capacity is 400W at 12V and 800W at 24V, so you can use one panel at 12V and up to three on 24V.Thank you for your interest.GordonGLR Industries, LLC

Depends on your battery set up...doubt one panel will get the job done. Works great for my RV though.

I have 2 panels, each puts out about 7 amps connected to this controller and could easily add more. Look at the specs on your panels and size your controller appropriately.

Yes, that's true ~. 2x30watt panels = 60 watts going to your controller. Good luck & have fun capturing the Sun. :-)
