5.2 or 14.3 kWh? Find Your Solar Battery
Meet our two Türkiye-manufactured LFP battery models, see how matching units add storage and compare simple examples of backup time.
Choose battery storage around the hours and appliances you want to support. Our two Türkiye-manufactured TommaTech modular LFP batteries offer a clear choice: smaller storage steps or more energy in one unit.
Compare the two products
| Modular G2 | Modular V Series | |
|---|---|---|
| Model | 51.2 V · 102 Ah | 51.2 V · 280 Ah |
| Listed energy per unit | 5.2224 kWh ≈ 5.22 kWh | 14.336 kWh ≈ 14.34 kWh |
| What it offers | Smaller steps when planning storage. | About 2.75 times the energy in one unit. |
| Product code | BTR-P-51.2V-102AH | BTR-P-51.2V-280AH |
Both use LiFePO4 chemistry, a battery management system and an LCD display. They belong in an approved low-voltage system; they are not high-voltage stack modules or batteries for a 12 V or 24 V inverter.
How do matching batteries add storage?
| Matching units in one bank | 102 Ah model | 280 Ah model |
|---|---|---|
| 1 | 5.22 kWh | 14.34 kWh |
| 2 | 10.44 kWh | 28.67 kWh |
| 4 | 20.89 kWh | 57.34 kWh |
These models support up to 16 matching units in parallel under the approved design, with no series connection. Parallel connection keeps the same nominal 51.2 V and adds energy. Do not mix the 102 Ah and 280 Ah models in one bank.
The installation also includes the approved power collection, protection and communication arrangement. An expansion needs a check of the existing system and settings; the unit limit is not a recommendation to install that quantity.
What could the capacity mean in hours?
At an assumed constant 500 W demand, one 102 Ah unit gives an illustrative 8.4 hours, two give 16.7 hours, and one 280 Ah unit gives 22.9 hours.
Which option should you compare?
Start with the 102 Ah model when smaller storage increments suit your plan. Compare the 280 Ah V Series when you want more energy in one unit. For higher appliance power, we also check how many units the bank needs: capacity in kWh alone does not determine its power delivery.
The 102 Ah model lists 75 A maximum discharge per unit; the 280 Ah model lists 140 A. The V Series manual illustrates two 280 Ah units for an inverter up to 11 kW. The exact inverter approval and operating limits remain part of the final selection.
