--- title: "Solar Batteries & Energy Backup | Bee Energy" description: "Energy storage systems with LiFePO4 batteries and power backup. Integrates with solar panels or works as a standalone system." url: https://beeenergycr.com/en/baterias-respaldo-energetico language: en --- Energy Backup # Power backup when the grid fails When the power goes out, your business or your home doesn't have to stop. We design and install backup systems with LiFePO4 batteries that keep your equipment running through outages, with no noise, no fuel, and no dependence on a generator. You don't need solar panels to have backup. The system works on its own, and it can also integrate with panels or a generator.

For commercial-industrial BESS (large systems of 10+ kWh) we work with modular configurations based on each project's specifications. Technical decision ## LiFePO4 or lead-acid: which is right for you? If you're comparing options, this is the difference that matters: Feature Lead-acid AGM/Gel LiFePO4 Initial investment Lower Higher Usable energy Only 50% to protect its lifespan Between 80% and 90%, depending on the manufacturer Life cycles\* 500 - 1,500 6,000 - 10,000 Space and weight Needs more space and weighs more More compact and lighter Efficiency Loses more energy while charging and discharging Makes better use of the stored energy Maintenance AGM and Gel need little maintenance; flooded types need periodic checks Zero maintenance Cost over its lifetime Requires more frequent replacements (2-4 years) At least 10 years before replacement Recommended use Limited budgets, occasional backup, or existing systems Daily use, self-consumption, frequent backup, and new systems \* One cycle is completed when the battery discharges from 100% down to its usable depth of discharge. **We recommend LiFePO4** for its greater usable energy, efficiency, and lifespan. Lead-acid can still be a good fit for existing systems or infrequent backup applications. Capacities ## Typical capacities by use Use Typical capacity Essential residential backup (fridge, lights, internet) 5 - 10 kWh Residential nighttime self-consumption 10 - 20 kWh Small commercial backup 15 - 40 kWh Industrial operational backup 50 - 250+ kWh Industrial peak shaving (T-MTb) sized case by case Reference values. Actual capacity depends on the electrical equipment to be backed up and the required backup hours. An honest assessment ## When it makes sense to add batteries Not always. Take this honest look: **It's worth it if:** - Your area has frequent power outages (more than 5-6 a year, or long ones). - You have critical equipment (cold rooms, medical equipment, servers). - Your business/industry is on an industrial rate with a demand charge. - You have a solar system and want to use the excess generation at night (greater independence). **It's less worth it if:** - The power supply in your area is very stable. - Your critical loads are low. - You don't want to add cost to the solar system and your priority is a short payback. ## Don't wait for the next blackout Your backup, ready when you need it.
