12. FAQ (Frequently Asked Questions)
● How to claim the warranty and extended warranty?
Please refer to the warranty card you received from where you have ordered
the product from. Any extended warranty, if purchased, will only take eect
after the default warranty has expired.
● Can the unit be upgraded?
When B300 has been connected to AC300, the rmware including ARM, DSP,
IoT and BMS can be upgraded online through OTA via BLUETTI APP.
● Can it be charged and discharged at the same time?
Yes, the unit supports pass-through charging function for DC outputs. We
recommend fully charging the unit at least once per month to extend the
battery life.
●Can I connected my two AC300 with Fusion Box to achieve double the output
power, voltage and capacity.
You can connect two AC300 units with a Fusion Box.
● Can I use third-party solar panels to charge the unit?
Yes, third-party solar panels can be used as long as they utilize MC4
connectors and the combined output voltage (in series or parallel) is between
55V to 145V. The maximum input power is 1,200W.
If the open circuit voltage of the panels are higher than 145V, but less than
550V, you may purchase the optional PV Module to step down the voltage to
enable solar charging.

● How do I know whether my appliance will work well with the power station?
Calculate how much the continuous loads are for your appliances in total. As
long as they do not exceed the rated output power of the power station, it
should work.
● How can I connect the product to my home circuit breaker box?
To install the grid-tie power system, a licensed electrician with a professional
technician certicate is required to connect the wires of critical equipment
loads from your main electrical box to the BLUETTI Sub Panel (optional
purchase).
