Frequently Asked Questions
Q
What is the difference between the FTW48 and FTW51.2 series batteries?
The FTW48 series operates at a nominal voltage of 48V with an operating range of 42~54.75V, while the FTW51.2 series operates at 51.2V with a range of 44.8~58.4V. Both series are available in 100Ah and 200Ah capacities. The choice depends on your inverter's compatible voltage range.
Q
How many units can be connected in parallel, and what is the maximum total capacity?
Up to 15 units can be connected in parallel, achieving a maximum total energy capacity of 153.6kWh. This makes the system capable of powering 99% of household appliances, even during extended outages.
Q
What is the expected lifespan and cycle life of SOLARNO1 LiFePO4 batteries?
SOLARNO1 batteries use Grade A+ LiFePO4 cells with 6000+ charge-discharge cycles and a lifespan of 10+ years. This is more than 10 times longer than traditional lead-acid batteries, making them a highly cost-effective long-term investment.
Q
What communication protocols does this battery support?
The battery supports RS485, RS232, and CAN communication protocols as standard. Optional Bluetooth and WiFi connectivity are also available. Please communicate with our engineers if you require these optional features.
Q
Is this battery compatible with mainstream brand inverters?
Yes. SOLARNO1 solar generators are compatible with mainstream brand inverters available on the market. However, this product must be used with an inverter — it cannot be used as a standalone power source without one.
Q
What warranty and after-sales support is provided?
All SOLARNO1 LiFePO4 batteries are backed by a 5-year solution. This includes dedicated technical support and a seamless after-sales process. Mounting brackets, fixing screws, and power cables are included in the package, so no additional accessories are required for installation.
