Frequently Asked Questions (FAQ)
Q What is the difference between the FTR48 and FTR51.2 series?
The FTR48 series operates at a nominal voltage of 48V, while the FTR51.2 series operates at 51.2V. Both are available in 100Ah and 200Ah capacities. The higher voltage of the FTR51.2 series results in slightly higher energy capacity (5.12kWh and 10.24kWh respectively) compared to the FTR48 series (4.8kWh and 9.6kWh).
Q How many units can be connected in parallel?
Up to 15 units can be connected in parallel, allowing you to achieve a maximum total capacity of 153.6kWh. This makes the system scalable to meet a wide range of residential and small commercial energy storage needs.
Q What communication interfaces does this battery support?
The battery supports RS485, RS232, and CAN communication protocols as standard. Optional Bluetooth and WiFi connectivity are also available. Please contact our engineers if you require customized communication configurations.
Q What is the expected lifespan and warranty of this LiFePO4 battery?
SOLARNO1 LiFePO4 batteries use Grade A+ cells with 6000+ charge/discharge cycles, delivering a lifespan of 10+ years — more than 10 times that of traditional lead-acid batteries. The product is backed by a 5-year solution with dedicated technical support.
Q Is this battery compatible with third-party inverters?
Yes. This product is designed to work with mainstream brand inverters available on the market. It must be used in conjunction with an inverter. If you are unsure about compatibility with your specific inverter model, please consult our technical team before purchase.
Q What protections does the built-in BMS provide?
The built-in 100A Battery Management System (BMS) provides comprehensive protection including overcharge protection, over-discharge protection, over-current protection, overheating protection (cut-off above 75℃), and short circuit protection. It also maintains an excellent self-discharge rate to optimize overall battery performance and safety.
