What it is
A set of equipment that generates and stores energy independently of the electrical grid: a solar panel, batteries, an MPPT charge controller, and an inverter, which converts the energy from the batteries into the standard used by the other equipment. Circuit breakers protect the system from overload. It is the kind of off-grid solution used where there is no reliable electrical grid.
In TECER
It powered the TVWS CPE during the tests in Mosqueiro, with measured consumption of about 0.85 A (10 W), well below the 4 to 5 A (50 to 75 W) of the Starlink antenna used as a backup connection. The kit’s box, with its charge controller, inverter, and circuit breakers, was reassembled during the tests at LASSE/UFPA, with reorganized cables and a voltage, current, and power measurement system.
Voltage, current, power, temperature, and battery state were tracked by the monitoring stack set up for Phase 1.
