Description
Keep your essential devices powered with the Road Smart SRNE HP 500W Power Tank, an all-in-one portable solar energy storage system designed for dependable backup power and everyday energy needs.
Built around a 1004Wh LiFePO4 battery, the HP 500W combines energy storage, inverter technology, and solar charging in a compact unit. Its 500W rated AC output makes it suitable for powering a range of essential electronics, appliances, and work equipment during power interruptions or when access to grid electricity is limited.
Reliable LiFePO4 Battery Storage
The Power Tank uses a LiFePO4 (Lithium Iron Phosphate) battery, a battery chemistry known for its long service life, stability, and safety compared with traditional lead-acid batteries.
With 1004Wh of battery energy, it provides a practical reserve of stored electricity for essential devices and equipment.
500W AC Power Output
The integrated inverter provides up to 500W rated AC output at 230V, allowing you to run compatible electronics and small appliances without relying directly on the grid.
It can be useful for applications such as:
- Laptops and computers
- Wi-Fi routers and networking equipment
- LED lighting
- TVs and entertainment equipment
- Phone and tablet chargers
- Small electronic appliances
- Other compatible devices within the 500W rated output
Note: Actual runtime depends on the power consumption of the connected equipment.
Solar Charging with Built-In MPPT
The HP 500W supports solar charging through its integrated MPPT solar charge controller, allowing you to recharge the battery using compatible solar panels.
The unit supports:
- Maximum PV input power: 300W
- Maximum PV open-circuit voltage: 56V
- PV input voltage range: 11–55V
- Maximum MPPT charging current: 100A
This makes the system suitable for solar-powered backup applications where reducing dependence on grid electricity is important.
AC Charging
In addition to solar charging, the Power Tank can be charged from an AC power source. This gives you flexibility to recharge the battery from the grid when electricity is available and use solar power as an alternative charging source.
Compact and Portable Design
The Road Smart HP 500W has an integrated carrying handle and compact enclosure, making it easier to move between locations. Its portable design makes it suitable for home backup, offices, shops, outdoor activities, field work, and other situations where portable power is required.
