I have a motorhome with four 6 Vdc golf cart deep cell batteries that are wired in series. So the batteries produce 12 volts for the coach. Can I use grape solar panels to charge the 6 V batteries that are wired in series that produce 12 volts?
Asked by: Mike
Yes, but keep in mind you need a charge controller between the panels and the battery. The PWM controllers are popular with our panels since their voltages are perfect for charging 12V battery banks with a single panel or multiple panels connected in parallel. If you plan to use the more efficient (and expensive) MPPT controllers, you will need to connect at least two of these panels in series for most of that type of controller.

How do I wire them in parallel

do I have to buy an adapter
Asked by: Tom
connect positive to positive and negative to negative. the 10 gauage (awg) wire will carry up to 40 amps ( iuse a maximum of 6 panels pr run) as long as the itance is less then 30 feet (including all wires from the farthest panel to the charge controller and then to the batteries.). I currently have 5 panels on a 10 awg wire run for 30 feet, (multimeter shows .001 amp loss and .003 volt loss) that ties 2 more banks of 6 panels each to a 2 awg wires run 30 more feet to the charge controler and then zero awg from the controler to the batteries about 6 feet additional. and of course zero awg to a 5000 and a 2000 watt inverters... works perfectly for about 1 year so far. no noticable loss in power at any connection..

HOW MANY WATTS WOULD IT TAKE TO HOOKUP 30 AMPS?

HOW MANY WATTS WOULD IT TAKE TO HOOKUP 30 AMPS?
Asked by: SISSY
wattage is amps multiplied by volts, so 30 amps at 12 volts is 360 watts, 30 amps at 110 volts is 3,300 watts.. 30 x 12 = 360 ----- 30x110 =3300. If your on a 24 volt system 30x24 = 720 watts

Used for lighting (2 LED's),12 volt cooler, & other applications, in my camper. Both Home Depot & Grape Solar were great when original faulty panel needed to be exchanged! Great customer service!

Rated 5 out of 5 by from Very good value and well built I ordered 2 of these panels to replace some thin-film panels I purchased from another seller. For the price, these panels produce much more power ($/watt) and are much more solidly built. They are easy to mount and connect. The first panel was basically thrown into a box with little protection for shipment, but the second panel came in more protective packaging. Neither panel, however, arrived damaged. I have them paired (in series) with the Grape Solar 300W MPPT controller, also sold by Home Depot, to keep a small bank of 12V batteries charged - see pics. (Note: I can put them in series because the controller is MPPT.) Works wonderfully.

Rated 5 out of 5 by from Bought 4, all good I mounted them on a tilting rack, to follow the sun, manually. They do a fine job charging my 6 golf cart batteries on a sunny day. They charge a little on a cloudy day. The way I have them mounted, all 4 sets of wires come together in a beaker box. I cut the connectors off. Used 6-3 with ground wire. paired the conductors, red and black, for positive, white and ground for negative, for a better conduction 80 ft.

Rated 5 out of 5 by from price vs one 20 watt replace I have a cracked 20 watt panel of four. The price 2 replace it cost almost $100. Then still only have 80 watts.This way I only have to worry 1 panel to set up.And only appr. 20lb. Others are Heavy 40 to 50. These will go on the house with others for backup and I can add tv more lites when electric goes off. I will use the 100 watt grape for the camper. I have used it for 2 days at home,charged the battery in 4hrs it was 12.45 and went to 12.73 .I checked after letting it rest for 2 hrs .next day it was at 12.71... at capacity For it. This was on sale ...109.00

Rated 5 out of 5 by from Great portable solar panel I was looking for a solar panel that wasn't large and heavy but produced a decent amount of power. This one is exactly that. It's easy to transport and move around. I now charge my electric tractor batteries in the field with little effort. The panel is well made with top quality materials. I would definitely recommend it.

Rated 5 out of 5 by from Very Competitive price I am currently stockpiling these solar panels for a roof installation later this spring, weather permitting. The panels are a real value and have a good warranty. Many competitor panels are priced much higher and have a shorter warranty. Solar is rapidly becoming cost competive with fossil fuels!
