Questions & Answers
Can you charge electric generator with this
This solar panel is designed for charging 12V batteries, such as those found in RVs, boats, and off-grid systems. It is not designed to directly charge an electric generator. Electric generators typically run on gasoline or other fuels and produce electricity through mechanical means. They are not designed to be charged by solar panels in the same way that batteries are.
What is the short-circuit current output and the open circuit voltage output?
The open circuit voltage is 22.0V and the short-circuit current is 3.17A. These specifications can be found under the specifications section of the product page.
Controller needed? My Ecoflow generator has the controller built in. I have 4/ 100 watt panels and just am looking for smaller panel for my small generator. What is the volt and amp output of this panel? Need to see if it is compatible .
what do i need to use this to charge Portable power station
You will need to reach out to the manufacturer of your power station to find out the input requirements for their device.
you will need a charge controller possibly the schumacher spc-7a. It is a 7amp controller and if you stay with the one 50watt panel you are well within the limits. 50w/ 12 volts= 4.1 amps. I bought one and then did not use it because I decided to buy a 2nd panel which put me over.
Is there any danger that it may cause fire or burning?
As with any electrical components, the use of properly sized fuses or breakers (10-15A on the DC side) should minimize any danger of fire.
If you do not fuse the leads from the panel, going to the charge controler and the charge controler was to fail with a dead short from your 12 Volt battery system and the blocking diod, in the panel was also to fail and not block the backfeed, then you could have a fire. Fusing is always recomended and an automotive 5 amp, 7 1/2 amp or 10 amp fuse MAX will give you the protection you need. In the past 10 years I have never had a blocking diode fail or a charge controler die in a shorted condition, but it could happen so fuse, fuse ,fuse. and don't forget the fusing to the charge controler from the battery.
As it simply plugs into existing house wiring it will be covered by house breaker panel. It doesn't develope that much heat but I certainly would give it some ventilation room
What size transfer pump can I run
It is highly unlikely the 50-Watt panel would produce enough power for a transfer pump (depends on the Wattage and time of use of your transfer pump). Don't hesitate to contact Grape Solar at info@grapesolar.com for assistance in sizing an Off-Grid kit for your transfer pump.
Im really curious about how this would work in powering power bank. Specifically a jackery 240 is what im running, but just a single person <500w power bank I just want a ballpark. Im purchasing it with the hope that it will charge my jackery 240 in 10-12 hours as I have consistently found slightly better on-the-go solar panels that are 60w (18v?) that seem to charge the jackery between 7-9hrs. If I could do the conversion myself I would but I cant confidently.
The 50 watt Grape Solar panel is 2.75 amps per hour at 18 volts. If you have an 18 amp hour glass mat battery, it would take about 6-7 hours of full sun following the sun the whole time. If you have 2 - 12 hour batteries, it would take 8 - 9 hours following the sun full time. A 35 amp hour battery would take 14 -15 hours of full sun to fully charge with one 50 watt panel. if the panel is static and does not follow the sun you would get about 175 watt hours or about 10 amp hours of charge at 18 volts.
How would I connect this via DC to charge a portable battery that takes a maximum of 15V? What connectors or cables are needed?
For that you will need a charge controller. I recommend our 50W kit, which comes with a charge controller and cables.
