Product Details

Our lightweight, portable solar power generator utilizes the finest technology obtainable. Powerenz LFP40 takes advantage of a Lithium Iron Phosphate (LFP) battery that weighs 40-50% less than a lead acid battery of the same capacity, and that will provide at least 2000 charge/discharge cycles before its performance decreases.

Powerenz LFP40 utilizes Maximum Power Point Tracking (MPPT) solar charging which optimizes the electronic relationship between solar panel and battery. This can accelerate the rate at which the battery can be solar-charged by up to 30%.

Powerenz LFP40 can be carried during events where power and low weight are critical. Powerenz LFP40 provides power for electronics that require 12 volts DC up to 10 amps/120 watts, 120 volts AC up to 300 watts, and that can recharge itself in sunlight using the included folding solar panels. This system is best suited to provide power for electronics, such as cell and satellite phones, communication radios, laptop computers, small battery chargers, night vision systems, satellite repeaters, lighting fixtures, small power tools, televisions, GPS’s, flashlights, small refrigeration/freezer units, and more.

The battery, solar charge controller, power inverter, wiring, AC-powered battery charger, extension cable that connects the solar panel to the battery pack, and accessories are enclosed in a water-resistant sling pack. The solar panels are carried separately. 12-volt DC power is accessible via a female cigarette lighter socket that plugs into the battery. 120-volt AC power is provided by an inverter that plugs into the battery.

Powerenz LFP40 - 176-Watt Sling Pack includes: B attery - rechargeable, 12.8-volt, 40 amp-hour, 512 watt-hour LFP unit. The battery can be charged directly from the solar panels or from the included smart, 3-amp, 100-240VAC-powered charger when the grid is available. The AC recharging time is 14-15 hours from empty to full. To recharge the battery more quickly when the grid is available, a 10-amp AC-powered battery charger may be substituted for the 3-amp charger. Please call us at 770-639-2244 to discuss.

Solar panels –two identical hi-efficiency, water (IP65)- and weather-proof, folding solar panels that come in digital ACU camouflage or green-brown jungle camouflage on their external surfaces, and that have the following output ratings at maximum power: 88 watts; 5.165 amps; 17.024 volts. The inner surfaces that surround the solar cells are white. Their open circuit voltages are 20.38 volts, and their short circuit currents are 5.727 amps. These superior panels are manufactured in the USA using high-quality monocrystalline solar cells, the rated efficiency of which is 18.4%. Each fold out solar panel weighs 8.1 pounds, and measures 23 x 12 x 2 inches folded, and 48 x 23 x 1/8 inches unfolded (7.03 square feet). Extension cables are included. In each corner of each panel, there is a metal ringlet that can be used to secure the panel.

The camouflage pattern covers the external (non-solar cell side) surface of the foldable solar panel. On the solar cell side, the space between and around the cells is white to keep the panel cooler and to increase its efficiency.

Solar Charge Controller – 10.5-amp/140-watt MPPT unit. The solar charge controller is protected by a circuit breaker that can also be used as an ON-OFF switch. If the system is to be stored for a prolonged length of time, the circuit breaker should be switched to the OFF position and/or the battery should be charged every 2-3 months in order to prevent complete drainage of the battery. To solar recharge the battery pack, the circuit breaker must be switched to the ON position.

Backpack – Maxpedition Malaga Sling Pack

Power Inverter: continuous 300-watt (5-second peak 400 watts), modified sine wave unit that has 2 AC receptacles. The power/current output from the inverter is limited to 30 amps/360 watts by a fuse.
