Kenya Telecom Solar-Storage — 40kWh Off-Grid

Project overview

In Kenya, telecom base stations in remote areas without utility grid access needed power that did not depend on a grid connection. The case record describes a fully off-grid system with solar as the primary source and battery supply for 24/7 operation, replacing diesel generation under normal operating conditions.

Applications at this site

• Telecom base station power in remote, gridless areas
• 24/7 off-grid operation with solar priority
• Diesel-replacement for base station power

Installed capacity

• Energy storage: 40 kWh outdoor base station energy cabinet (per the configuration table; the record’s main-equipment table lists 200 kWh — the configuration-table value is used here, and the discrepancy is flagged for confirmation with HighJoule)
• Solar PV: configured according to storage capacity and local site conditions
• Battery: LiFePO4, more than 6,000 cycles, Grade-A cells

Project advantages

• Fully off-grid: operates independently of the national power grid.
• Solar-priority dispatch: PV supplies the load during daylight and stores surplus; battery supplies power at night or in low insolation.
• Remote monitoring: FSU unit with web-based management and SNMP; 4G wireless sensor module for unattended sites.
• Hot-climate design: DC 48V compressor-type air conditioner with RS485 communication.
• Emergency backup: optional diesel generator accessories for backup only.
