Energy storage product for B2B applications
View Details →
Advanced energy storage product engineered for reliable power applications, scalable supply, and global B2B project requirements.
Keep phones, cameras, camp lights and other compatible low-power gear running at a campsite. The SRYG-500 delivers 500W rated AC output, with USB, Type-C and 12V DC ports for flexible outdoor charging.

Bring portable power to rest stops and vehicle-based trips for phones, cameras, and compatible 12V devices. Check each device's power requirements and keep AC loads within the 500W rating.

During brief outages, power selected essentials such as LED lights, phones, a router or other compatible low-power electronics. Prioritize critical devices; runtime depends on actual load and available stored energy.

Recharge from a compatible 13–20V solar source and support field equipment such as camera batteries, phones, and a laptop. Solar input is rated at 5A, up to 8A maximum; charging conditions affect results.
