Q:what do i need to use this to charge Portable power station
by|Oct 31, 2020
2 Answers
Answer This Question

A:  You will need to reach out to the manufacturer of your power station to find out the input requirements for their device.

    A:  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.

    Q:Is there any danger that it may cause fire or burning?
    by|Sep 30, 2020

    Answer This Question

    A:  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.

    by|Dec 27, 2020

      A:  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.

      A:  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

      Q:What size transfer pump can I run
      by|Aug 2, 2020
      1 Answer
      Answer This Question

      A:  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.

        Q: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.

        1 Answer
        Answer This Question

        A:  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.

        Nice solar panels for a good price
        I purchased 2 of these panels to make a solar suitcase. I got them on sale for $70 a piece which was the best price I could find. They are working well and I am charging 2 35AN AGMs with them. I plan on powering a 12V Truckfridge to have cold stuff when I travel. Here is a picture of my test setup.

        This solar panel is a reasonable size, and it works well for maintaining a charge on the batteries. In my personal opinion, I would like it to be a little more sensitive to low light, but that may just be the nature of solar panels in general.

          Grape solar makes great stuff, I’ve had some of their panels for several years and have been through multiple hail storms that damaged RV and vehicles breaking windows, the panels were unscathed and work perfectly to this day
