Sherpa PEAK 1.8 - Available March 28th
The PEAK 1.8 is a versatile portable power station, delivering reliable energy wherever you go, even in freezing conditions. Compact yet robust, it delivers ample power for a wide range of devices, from small electronics to higher-demand appliances. Built with a durable exterior and a user-friendly interface, the PEAK 1.8 is the ideal companion for camping, vanlife, home backup, and professional use. Its integrated MPPT charge controller allows for efficient solar charging, enabling you to harness renewable energy and stay off-grid for longer. The PEAK 1.8 is equipped with a pure sine wave inverter, capable of powering appliances and devices in situations where there is no access to mains power. It has a Backup Power Supply function, allowing your appliances to use grid power via the unit and switch over to battery power in 8-20 milliseconds in case of a power cut.
Battery information
The PEAK 1.8 is powered by high-quality, automotive-grade lithium iron phosphate (LiFePO4) batteries. Renowned for their safety and longevity, these cells can be cycled 3500 times before the original capacity drops to 80%. With a capacity of 1024Wh, and optional expansion to 4096Wh, the PEAK 1.8 offers a substantial energy reserve. Its advanced Battery Management System (BMS) provides comprehensive protection against over-voltage, low-voltage, overheating, overloads, and short circuits, ensuring safe and reliable operation while maximising the lifespan of the battery. The PEAK 1.8 also features an automatic battery cell heating function, which activates when charging in temperatures below 0°C (32°F), allowing for safe and effective use in colder climates.
Output
Boasting 11 power output ports, the PEAK 1.8 enables you to power multiple devices
simultaneously:
AC OUTPUT: AC Sockets x 3 (220V-240V/50Hz) for running high-power mains appliances
DC OUTPUT: The panels comprise multiple smart-charge ports that self-regulate the power your devices need: USB-A Port x 2, USB-C Port x 2, DC 5525 Port x 1, Wireless Charging Pad x 1, Aux Car Port x 1 and XT60 Output x 1, allowing you to charge and power smartphones, cameras, laptops, fridges, diesel heaters, and other DC powered devices.
Charging
The PEAK 1.8 offers flexible and fast charging options to suit your situation:
AC Charging: Recharge from 0% to 100% in approximately 1 hour 15 minutes from a standard wall
outlet.
Solar Charging: The built-in high-efficiency MPPT controller allows for solar charging via the XT60
port (11-60V, up to 600W). You can achieve a full charge in around 1 hour 40 minutes with optimal
solar input.
Vehicle Charging: Replenish the battery while driving using the included 12V car charging cable in 10
hours. For a faster charge, the optional CHARGE-500 can fully charge the unit in approximately 2
hours from a vehicle's auxiliary battery.
