Answer: 
You need batteries, charge controller, and an inverter. These panels are most efficient on a 24 volt DC system, and still require a DC to AC inverter

Answer: 
You'll need a charge controller, inverter and batteries. I suggest you do more research into solar power. It can be somewhat involved, but once set up. you're good to go as long as you have enough sunlight. You'll probably also want a backup generator for the dark days. One of these panels will run 32 watts, no problem. If you want to run heavier power tools, you'll need more watts and bigger everything Read More

Answer: 
Hi tdw2676,
Thank you for your interest in Grape Solar.
You would need an MC4 cable cut in half to connect to the MC4 connectors on the panel. That cable would go to an MPPT charge controller like the Morningstar TS-MPPT-45. From the charge controller you would want 10AWG cable to a 12V deep cycle battery. From the battery, use 10AWG cable to an inverter like the Xantrex 450W. You will also need Read More

A more cost effective solution would be our GS-200-KIT. It includes everything you need, except the battery and mounting hardware, and it is at a better price than a kit that would use a 280W panel. Read Less

Answer: 
Without knowing the specifications of the battery its hard to say but typically 24 volt lead acid batteries can be damaged with prolonged charging at high voltage, and this panel in low ambient temperatures can exceed 36 volts. In addition if a battery is overcharged for an extended period it can catch fire. A quality mppt charge controller will make the most efficient use of this solar panel.

Answer: 
Yes. If you don`t have a controller then you can ruin your battery pack by over chargin your batterys.This 280 watt panel puts out 37 volts at 7.7 amps on a good sunshinny day.The controller will tell the solar panel when the batterys are fully charged and will stop charging untill the battery voltage drops down below normal and then will start to charging again.

Hi Harley,
Thank you for your interest in Grape Solar panels.
In the majority of cases a charge controller is required to properly charge your battery pack. Without a charge controller you run the risk of damaging your batteries and either shortening their lifespan, reduce their capacity or even starting a fire.

The Sunforce MPPT 12/24-Volt 20 Amp charge controller will work with one or two panels in parallel. If you plan on using more panels, you will need to order a larger MPPT charge controller through your local Home Depot Pro Desk. Read Less

Rated 5.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Plenty of power Two of these panels are giving us as much power as our tracker array of 10 panels. Yes, the panels on the array are smaller and around 14 years old, but doubling our power with just two of these guys is a boon for us. I used to have to run the aux generator when working in my shop making Laughing Crow Flutes, but now the generator sits idle most of the time, saving us gasoline and wear and tear on "Gennie". We plan to upgrade the array on the tracker with 4 more of these panels after winter and up the wattage to three times the power we had before starting the upgrade. We live in an Earth Ship outside Taos New Mexico, so almost all our power comes from solar. We have back up generators for the dark days, but even on a cloudy day, we're getting up to a good 100 watts from the two new panels. When the skies are clear and the sun is overhead, we're cooking. The price is comparable to all the other options and the free shipping is a plus. We're very pleased with the results. December 10, 2013
Rated 5.0 out of 5.0 by Took 2 weeks to recieve but worth it Bought 2 of these for boon docking in my RV. Only complaints I have is packaging is pretty sad and it took 2 weeks to be received. Surprisingly did come without damage as the panels were only protected by a thin sheet of cardboard. HD was very helpful in tracking packages as they come factory direct through a company called estes express. These panels do weigh about 80 lbs apiece so keep that in mind when ordering. March 31, 2014
Rated 5.0 out of 5.0 by Out performs its specifications I currently have four of these, and according to current and voltage numbers generated from the charge controller I have seen up to 380 watts produced in full sun with ambient temps in the mid seventies. I will probably buy more. April 25, 2014
Rated 5.0 out of 5.0 by High output on a cloudy day output V. was 8V. & 1.8 A on a very,very cloudy day.The third day was very clear & bright.The PV provided 7.7 amps at 48 V.Burned out my small 12 volt battery charging controller.Unless my meter was defective, this unit was providing 369.6 watts to the controller & 6 12V batteries.I`m going to need a much larger controller. December 25, 2012
Rated 5.0 out of 5.0 by Solid construction and easy to install Works as advertized.It powers my camper battery bank with power to spare. July 8, 2013
Rated 5.0 out of 5.0 by 280watt polycrystalline panel Panel is great , I use with tie grid inverter , takes longer time to get it , but made very good . August 4, 2013
Rated 5.0 out of 5.0 by Mounted on VW camper for backwoods camping & Festivals The best thing is that Home Depot can ship these for 50 bucks. If only buying one panel many places charge 50% of cost for shipping. October 20, 2012
