Plug Sierro into a properly grounded 120V wall outlet, turn it on with a 0.5-second press, then connect your essential devices to the AC output ports. No electrician or rewiring is required.

Keep at least 2 inches (50mm) of clearance around every ventilation opening.

The four white LEDs show battery level in 25% increments. While charging, the current level stays illuminated and the next level blinks. During discharge, the indicators turn off from top to bottom as the battery level decreases.

The serial number is printed on the product label. Keep it available when registering your product or contacting support so our team can identify the exact unit.

Each Sierro 1000 or Sierro 2000 includes the power station, an AC charging cable, a User Manual, and a Warranty Card.

Sierro can power common household devices such as refrigerators, WiFi routers, fans, TVs, monitors, laptops, phone chargers, desk lamps, and pet care equipment.

Keep the total connected load within 500W for Sierro 1000 or 1000W for Sierro 2000. Appliances with compressors can draw more power during startup and should be tested before unattended use.

When utility power is available, connected devices run from the grid. During an outage, Sierro switches to battery power in 15ms or less so typical household electronics can continue running without a manual restart.

It is not intended for servers, data centers, life-support equipment, or devices that require professional-grade conditioning or 0ms transfer.

Confirm that the original charging cable is being used, the unit is switched on, and the battery is not below 25%. Make sure the connected load is within the model's rated output. If a red fault indicator is present, turn the unit off and restart it after it has cooled.

Yes. Both models accept 12-55V DC solar input through an MC4-to-XT90 cable. Maximum solar input is 300W for Sierro 1000 and 550W for Sierro 2000.

Never exceed 55V. Damage caused by incompatible panels or incorrect connections may not be covered by warranty.

Yes, provided the panel array stays within the supported 12-55V input range and uses the correct MC4-to-XT90 cable. Sierro 1000 supports up to 10A and Sierro 2000 supports up to 15A.

Sierro prioritizes solar charging when sufficient solar power is available. If solar input falls below approximately 50W, it switches to AC charging and periodically checks whether solar input has recovered.

Charge and operate Sierro between 32°F and 104°F (0°C-40°C). For best battery performance, use it around 68°F to 86°F (20°C-30°C).

A steady red indicator means Sierro stopped output because of a condition such as overload or internal overheating. Unplug connected devices, hold the power button for 3 seconds to turn the unit off, wait 10 minutes, then restart it.

If the red light returns, stop using the product and contact Sierro Support.

Store it indoors in a clean, dry, ventilated place. Every three months, discharge to 20%, charge to 100%, then discharge to approximately 60% for storage. Battery damage caused by more than six consecutive months without charging or discharging is not covered by warranty.

No. Sierro is rated IP20 and should be used indoors in a dry environment. Keep it away from rain, water, condensation, excessive humidity, and direct exposure to outdoor conditions.
