Off-Grid Solar Power System

This system will deliver a maximum of 180 watts/15 amps of power via each of two 12-volt cigarette lighter sockets, 140-150 watts of continuous 120VAC/60Hz pure sine wave power via a power inverter, and is wired and fused accordingly. The maximum combined deliverable power at any given moment is approximately 300 watts, limited by the drop in the battery voltage at a discharge current of approximately 25 amps, and is protected against over-current by a 30-amp ATC fuse. If the combined power draw of your electronic devices is 60 watts, the battery will last approximately 4 hours in the absence of incoming solar power before it needs to be recharged, longer if the power draw is less. If the current draw from either of the cigarette lighter sockets exceeds 15 amps, a 15-amp ATC fuse will blow, and will need to be replaced (simple to do; extras included). If the power draw from the inverter exceeds its continuous or surge wattage ratings, it will turn off, and then will need to be re-set (switch inverter power button off, then back on), or a 20-amp ATC fuse will blow and will need to be replaced (extras included).

The battery, solar charge controller, power inverter, 12-volt DC power distributor, wiring, and accessories are housed in a water-, crush-, and dust-proof, protective carrying case in black. The power system components are secured and padded inside the case by custom-configured cubed foam. The solar panel remains outside of the case. Off-Grid Solar Power System - #1 comes with: Battery: 26 amp-hour (312 watt-hour), adsorbed glass mat, sealed lead acid. Solar Charge Controller: 7-amp unit that is protected by a 7.5-amp ATC fuse. Power inverter: continuous 150-watt, pure sine wave unit that is protected by a 15-amp ATC fuse. Solar panel: one foldable 72-watt unit that weighs 6.4 pounds, and that will require 5-6 hours of peak sunlight to recharge the battery from empty to full. To charge the battery via a standard AC receptacle, included is one 3-amp, AC-powered battery charger. To charge the battery via an automobile 12-volt DC cigarette lighter socket, included is one male DC plug with cable.


The case measures 18.50 x 14.06 x 6.93 inches in external dimensions, and the entire system weighs approximately 37 pounds.


This system will deliver a maximum of 180 watts of power/15 amps via each of two12-volt cigarette lighter sockets (limited by 15-amp fuses), 150 watts of continuous 120VAC/60Hz power via an inverter (limited by the inverter circuitry), and is wired and fused accordingly. The maximum combined deliverable power at any given time is 360 watts/30 amps, and is limited by a 30-amp ATC fuse. If the combined power draw of your electronic devices is 60 watts, the battery will last approximately 3.5-4 hours in the absence of incoming solar power before it needs to be recharged, longer if the power draw is less. If the power draw from either of the cigarette lighter sockets exceeds 180 watts, a 15-amp ATC fuse will blow, and will need to be replaced (simple to do; extras included). If the power draw from the inverter exceeds its continuous or surge wattage ratings, it will turn off, and then automatically reset itself, or a 20-amp ATC fuse will blow and will need to be replaced (easy to do; extras included).

The battery, solar charge controller, power inverter, 12-volt DC power distributor, solar panel, wiring, and accessories are housed in a water-, crush-, and dust-proof, protective carrying case in yellow. The power system components are secured and padded inside the case by custom-configured foam. Off-Grid Solar Power System - #2 comes with: Battery: 26 amp-hour (312 watt-hour), adsorbed glass mat, sealed lead acid. Solar Charge Controller: 7-amp unit protected by a 7.5-amp ATC fuse. Power inverter: continuous 150-watt, modified sine wave unit. Solar panel: one foldable 72-watt unit that will require 5-6 hours of peak sunlight to recharge the battery from empty to full, and that weighs 6.4 pounds. To charge the battery via a standard AC receptacle, included is one 3-amp, AC-powered battery charger that is protected by a 5-amp ATC fuse. To charge the battery via an automobile 12-volt DC power socket, included is one male DC plug with cable.
