Frequently Asked Questions
Q1: Is this an all-in-one balcony power plant with direct AC output for balcony storage?
A: No. This is a split-type wall-mounted home energy storage LiFePO4 battery. No built-in AC inverter inside. It must be connected to an external 48V hybrid inverter and cannot output AC power directly from wall socket.
Q2: What is the internal structure? Is it a standard 16S series 48V LiFePO4 ESS battery?
A: NOT 16S configuration. Adopting special low-voltage boost topology for balcony storage market. Internal cell pack is 5S1P 314Ah Grade A+ LiFePO4 with raw voltage 16V. Equipped with built-in high-efficiency DC-DC step-up converter to output 48V system voltage, usable energy 5kWh.
Q3: How many units of this balcony storage battery can be connected in parallel for capacity expansion?
A: Maximum 6 units can be paralleled to expand total capacity of your home solar ESS system.
Q4: Can I mix new and used batteries in parallel?
A: Yes. This wall-mounted LiFePO4 ESS supports new-old battery mixing parallel connection.
Q5: Which inverters are compatible with this 48V DC-DC boost balcony storage battery?
A: Designed for standard 48V hybrid solar inverters with CAN / RS485 communication, such as Growatt, Goodwe, Deye, SofarSolar, Voltronic, Victron, SRNE, Megarevo, PYLONTECH, Luxpowertek, Sorortec, SMA, GINLONG, MUST, TBB, STUDER, Solis, etc. (Contact us for compatibility with other inverters)
Q6: What communication interfaces are available for this home LiFePO4 energy storage battery?
A: Dual-port CAN / RS485 for hybrid inverter connection, plus Bluetooth for mobile APP monitoring.
