Project Overview
Project Type: Off-grid solar + storage system for a residential home in the Philippines
Equipment Selected: 2 x LVFU 51.2V 280Ah floor-standing batteries (total capacity approx. 28.6kWh)
Inverter: Customer’s own existing inverter (fully compatible)
Operating Model: During the day, solar panels generate power and charge the batteries with any surplus. At night, the batteries discharge to power household loads – providing 24/7 clean electricity coverage.
Customer’s Needs
This household relies entirely on solar power for its daily electricity needs, with no grid connection available. The customer already owned an inverter, but the existing battery capacity proved insufficient – leading to unstable nighttime power supply. In other words, the storage system often fell short exactly when the family needed it most. The customer’s core requirement was straightforward: increase storage capacity without replacing the existing inverter, ensuring reliable nighttime power for the entire household.
Why Did the Customer Choose LVFU?
After comparing several brands, the customer selected LVFU for three key reasons:
1. Perfect communication compatibility – Our 51.2V 280Ah batteries support mainstream inverter protocols, so they required no additional modifications. They worked seamlessly with the customer’s existing inverter – truly plug-and-play.
2. Large capacity and long cycle life – Each battery provides 28.6kWh of storage. With two units connected in parallel, the total storage capacity easily covers the household’s entire nighttime load.
3. Floor-standing design – clean and simple – The batteries do not require wall mounting. They sit directly on the floor, making installation quick and straightforward. Moreover, their clean appearance blends well with the home environment.
Installation and Commissioning
We connected the two LVFU 51.2V 280Ah floor-standing batteries in parallel to the customer’s existing inverter system. The installation process went extremely smoothly – after connecting the communication cables, the system automatically recognized the battery parameters without requiring complex configuration. From unboxing to grid-tied operation, the entire commissioning process took just half a day. The customer’s existing inverter correctly identified the battery bank, and the charge/discharge logic has operated stably ever since, with seamless system switching.
Operational Results
After commissioning, the system delivered the following real-world performance:
- Total storage capacity: 57.2kWh (two units in parallel)
- Usable capacity (at 80% DoD): approximately 45kWh
- Nighttime power duration: Covers the entire home – including air conditioning, refrigerator, lighting, and appliances – throughout the night without any interruption
- PV utilization rate: Significantly improved – surplus daytime generation now goes entirely into storage instead of being wasted
- System status: Stable communication, BMS operating normally, and the customer reports full satisfaction
Customer Feedback
“After installing the LVFU batteries, our home finally has stable power. I used to worry every night about running out of electricity. Now we can run the air conditioning all night without a care. And the best part – we didn’t have to replace the inverter. Just connected it and it worked – so hassle-free.”
Conclusion
This Philippines home storage case clearly demonstrates one important lesson: choosing a storage system does not always mean replacing everything. LVFU’s 51.2V 280Ah floor-standing batteries offer excellent protocol compatibility, allowing them to flexibly match the customer’s own inverter. This approach helps users upgrade and expand their storage systems at minimal retrofit cost. Whether for new installations or existing system upgrades, LVFU provides reliable battery solutions that deliver peace of mind.
