A Ready-to-Use Home Energy Storage System BESS 2512B

INFOSAT BESS 2512B
A Ready-to-Use Home Energy Storage System for Energy Savings and Backup Power
The INFOSAT BESS 2512B is a compact home energy storage system combining a 2.5 kW off-grid hybrid inverter with a 12.8V 200Ah LiFePO4 battery, providing approximately 2.56 kWh of nominal energy storage.

When connected to compatible solar panels, the system stores solar energy for use during the evening, at night, or when sunlight is unavailable. This helps reduce electricity purchased from the grid while providing backup power during outages.

The system is suitable for essential household appliances and may support an air conditioner rated up to 12,000 BTU, provided that its actual operating power, startup current, and the total connected load remain within the inverter’s limits.

All major components are neatly installed on a mobile mounting frame, making the system organized, easy to move, and convenient to maintain.

Key Features

• 2.5 kW off-grid hybrid inverter

• Integrated electrical distribution and protection equipment
• Mobile frame with caster wheels
• Two-year inverter warranty
• Five-year battery warranty, subject to company terms and conditions
• How the System Can Reduce Electricity Costs
• When solar panels are connected, the system can use solar power for household loads and store surplus energy in the battery. The stored energy can then be used in the evening or at night, reducing the amount of electricity purchased from the grid.

Where a Time of Use tariff is available, the system may also be configured to charge during lower-cost periods and supply stored energy during higher-cost periods.

A battery does not generate energy by itself. Actual savings depend on the charging source, solar-panel capacity, available sunlight, household consumption pattern, electricity tariff, system settings, and conversion losses.

Illustrative Savings Example
Nominal battery energy:

12.8V × 200Ah = 2.56 kWh

If approximately 2 kWh of grid electricity is displaced each day and the illustrative electricity rate is THB 4.50 per kWh:

Estimated saving: THB 9 per day
Estimated saving: THB 270 per month
Estimated saving: THB 3,240 per year
This example is for general illustration only and is not a guarantee of actual savings. Usable battery capacity, system losses, charging cycles, electricity rates, and operating conditions vary between installations.

Frequently Asked Questions
1. Can the BESS 2512B really reduce my electricity bill?
Yes, when it is charged by solar energy or by lower-cost electricity and discharged during higher-cost periods. Actual savings depend on solar capacity, sunlight, electricity tariffs, household consumption, and system settings.


2. Can the system operate without solar panels?
Yes. The battery may be charged from grid electricity and used as backup power. However, charging and discharging at the same flat electricity rate may not produce meaningful bill savings.

3. Are solar panels included?
No. Solar panels are not included and must be selected according to the installation area, energy demand, and system design.

4. Which appliances can it power?
It can support common appliances such as lights, fans, televisions, internet routers, computers, and refrigerators. The combined operating load must remain within the inverter’s rated capacity.

5. Can it run an air conditioner?
The product is recommended for an air conditioner up to 12,000 BTU. The installer must verify the unit’s actual operating power, startup current, compressor type, and other loads operating at the same time.

6. How long will the battery last during an outage?
Runtime depends on the connected load. Assuming approximately 2 kWh of usable energy:

A 200W load may operate for approximately 8–10 hours.
A 500W load may operate for approximately 3–4 hours.
A 1,000W load may operate for approximately 1.5–2 hours.
Actual runtime may be shorter due to conversion losses, battery condition, temperature, and discharge settings.

7. Can it back up the entire house?
Backing up the entire house is not recommended without a professional load assessment. Essential circuits—such as lighting, refrigeration, internet equipment, and phone charging—should be prioritized for longer and safer operation.

8. What are the advantages of a LiFePO4 battery?
LiFePO4 batteries offer good thermal stability, safety, and generally longer cycle life than conventional lead-acid batteries. They also require no distilled-water maintenance. Actual battery life depends on temperature, depth of discharge, and operating conditions.

9. Can the inverter power appliances while charging the battery?
A hybrid inverter is designed to manage power from multiple sources. The actual operating mode depends on system configuration, available power sources, and installer settings.

10. Is professional installation required?
Yes. Installation and commissioning should be performed by a qualified electrical or solar technician to ensure correct cable sizing, grounding, circuit protection, and backup-load configuration.

11. What maintenance is required?
Periodically inspect electrical connections, cables, breakers, ventilation, and battery status. The system should be installed in a dry, well-ventilated area away from water, direct sunlight, and excessive heat.

12. What is the warranty period?
The inverter carries a two-year warranty, while the battery carries a five-year warranty, subject to the company’s warranty terms, installation requirements, and exclusions.
