300W 896Wh Off Grid Solar Energy Storage System LiFePO4 Micro Node

Off-Grid Energy System Overview

The PS-896WH-300W-Q is a compact off-grid solar energy storage system combining an 896Wh LiFePO4 battery, a 300W pure sine wave inverter, an integrated battery management system and an MPPT solar charging controller.

Designed for low-power remote applications, the system can provide independent electricity for communication equipment, monitoring devices, security cameras, LED lighting and selected field electronics where a stable grid connection is unavailable.

Its integrated structure reduces the number of separate components required for small solar installations and supports AC charging, solar charging or simultaneous AC and solar input.

Integrated Off-Grid System Configuration

Off-Grid Technical Profile

Typical Remote Power Applications

Remote Monitoring Equipment

Provides stored energy for compatible environmental sensors, data collection devices, low-power monitoring terminals and other remote electronics.

Security and Surveillance Systems

Can support selected low-power cameras, routers, communication equipment and LED lighting in temporary or isolated locations.

Remote Cabins and Work Sites

Suitable for small cabins, temporary work areas, inspection points and field stations requiring basic AC and USB power.

Emergency Communication Backup

Provides temporary backup electricity for compatible radios, routers, mobile devices and communication equipment during grid interruptions.

Load and Runtime Planning

Available operating time depends on the connected load, inverter efficiency, ambient temperature and battery condition. As a general planning reference, runtime can be estimated by dividing usable battery energy by the continuous device power.

For continuous off-grid operation, the daily energy consumption of the connected devices should be compared with the expected daily solar generation and available battery reserve.

Solar Panel and Deployment Notes

• The connected solar panel open-circuit voltage must not exceed 56Vdc.
• The recommended MPPT operating range is 10–55Vdc.
• Confirm solar connector type and polarity before installation.
• The continuous AC load should remain below the rated 300W output.
• Check the starting power of motors, pumps and compressor-based equipment.
• The unit is not specified as weatherproof and should be installed in a dry, ventilated and protected environment.
• Confirm the required AC voltage, frequency and socket configuration before ordering.

Procurement and Deployment FAQ

Why select an integrated off-grid energy storage unit?

The battery, inverter, BMS and MPPT controller are installed in one system, reducing the number of separately selected components required for small remote power applications.

Can the unit support sensitive monitoring equipment?

The pure sine wave inverter is suitable for many compatible electronic devices. Buyers should confirm the voltage, continuous power and starting power requirements of the equipment before deployment.

What solar panels can be connected?

Compatible panels must operate within the 10–55Vdc MPPT range, and their open-circuit voltage must remain below 56Vdc. Maximum solar charging power is 300W.

Can the system also be charged from an AC source?

Yes. It supports up to 300W AC charging and can also use AC and solar charging simultaneously, with maximum combined charging power of 400W.

Is the system suitable for permanent outdoor installation?

The available specifications do not indicate a weatherproof enclosure rating. The system should therefore be installed in a dry, ventilated and protected indoor cabinet or sheltered environment.

What should project buyers confirm before ordering?

Buyers should confirm daily energy consumption, peak load, equipment starting power, required backup duration, solar panel configuration, AC voltage, socket type, installation environment and packaging requirements.
