Solar Battery Backup Systems in Puerto Rico
Real energy independence during LUMA Energy outages. Specifically designed for Puerto Rico's conditions.
A solar battery stores your panels' energy so your home keeps the lights on when LUMA fails. Kilowatt PR installs solar systems with battery backup in all 78 municipalities of Puerto Rico, and every system we install includes one. After Hurricane Maria, many families were without electricity for weeks or months.
A solar system with battery storage works differently from a conventional grid-connected solar system. When panels produce more energy than you consume, the excess is stored in the battery instead of being exported to LUMA Energy. When panels don't produce enough (at night or during an outage), the battery provides the necessary energy.
We work mainly with EG4 lithium batteries and hybrid inverters. Our technicians and electricians with over a decade of experience in Puerto Rico size and configure each system for the loads you want backed up.
Backup hours = usable battery kWh divided by the average load in kW. The battery powers the circuits you choose to back up (refrigerator, lights, fans, internet, medical devices), and during the day the panels recharge it. For higher demand, more batteries give more hours, and a larger inverter lets more appliances run at once.
The installation includes a hybrid inverter that intelligently manages energy between the panels, battery, home consumption, and the LUMA Energy grid. The system automatically disconnects from the grid when it detects an outage, protecting LUMA technicians working on the lines, and automatically reconnects when service is restored.
