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.

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.

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

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.

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.
