01. AC300 Introduction
1.1. Introduction
●The AC300 system uses a dual-core controller (ARM controller + DSP controller)
which combines digital and analog signals perfectly to manage and control the
MPPT module, the AC Inverter module(Bidirectional topology,supporting AC
reverse fast charging), the DC-to-DC module. AC300 does not have a built-
in battery pack. You must match it with the B300 portable power station.
AC300 supports up to 4 B300 battery packs connected in parallel.
●This product integrates a solar charge controller, AC charge controller, AC inverter,
lithium battery and battery management system into one. It converts clean
and environmentally friendly solar energy and grid electricity into clean
electricity and sends it to all of your connected loads in your home.

02. General Safety Instructions
Please read this manual before operating.
●A licensed electrician is required to install the grid-tie power system as
involves connecting the wires of critical equipment from your main electrical
box to the BLUETTI Sub Panel (Optional Purchase).
●DO NOT place the power station near heat sources. It is prohibited to place
the equipment in an environment with ammable, explosive gas, or smoke. It
is also prohibited to operate the equipment in this environment.
●DO NOT attempt to replace the internal battery or any other component of
the equipment by anyone other than authorized personnel. There are no user
serviceable components.
●DO NOT operate in wet conditions. If the equipment becomes wet, please let
the unit dry completely before using.
●Please ensure proper ventilation while in use and do not obstruct fan openings.
Inadequate ventilation may cause permanent damage to the equipment.
●DO NOT stack anything on top of the power station either in storage or while
in use. DO NOT move the unit while operating as vibrations and impacts may
lead to poor connectivity to hardware inside.
●Warning:
DO NOT insert foreign objects into any ports of AC300 (both AC & DC & ventilation
holes). The power station generates the same potentially lethal AC power as
household wall outlet. Please use carefully and keep children away from it.
●If necessary, only dry powder re extinguisher is suitable for the product.
●For safety purposes, please use only the original charger and cables designed

03

for the equipment. We are not liable for damage caused by third-party
equipment and may render your warranty, invalid.
2.1. Installation (for grid-tie system)
●Before touching any conductor surface or terminal, measure the voltage of
the contact point to conrm that there is no danger of electric shock.
●After the equipment is installed, empty packaging materials such as cartons,
foam, plastic, cable ties, etc. should be removed from the equipment area.
●Except those who operate the equipment, please keep others away from the
equipment.

components, and cables. The risk of metal shavings entering the device can
cause short circuits on the circuit board.
●Wear goggles and protective gloves when drilling holes.
●The equipment should be shielded and protected during the drilling process
to prevent debris from falling into the equipment. After drilling, any and all
debris which may have landed on the equipment should be removed and
cleaned in a timely manner.
2.2. Installation environment requirements
●When the equipment is running, please do not block the vents or the heat
dissipation system in order to prevent high temperatures and/or res.
●The equipment should be installed in an area away from liquids. It is
