01. AC300 INTRODUCTION
1.1. Introduction
● The AC300 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 which uses a bidirectional topology
supporting AC reverse fast charging, and the DC-to-DC module. The AC300
does not have a built-in battery pack, requires at least one B300 connected,
and supports up to four B300 battery packs connected.
● 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

9.3. How to Calculate the Operation Time
●What is the depth of discharge (DoD)?
To extend the battery-life, the power station set the 90% DOD, which means that
only 90% of the battery capacity can be discharged. 10% of the energy is reserved to
avoid damage to the battery due to over-discharge.
η indicates local inverter eciency. DOD=90%, η =90%.
10. UPS
10.1. UPS Description
An uninterruptible power supply or uninterruptible power source (UPS) is
an electrical apparatus that provides emergency power to a load when the
input power source or mains power fails. A UPS differs from an auxiliary or
emergency power system or standby generator in that it will provide near-
instantaneous protection from input power interruptions, by supplying energy
stored in batteries, supercapacitors, or ywheels.
10.1.1. FYI (For Your Information)
Max. capacity retention indicates the limit of capacity of the unit that can be
recharged by grid, if you set the Max. battery capacity at 80% at Time Control
UPS Mode and Customized UPS Mode then AC300 could be charged to 80% via
grid. The rest of the 20% capacity will be recharged via solar panels.

preset High/Low battery capacity, AC300+B300 will stop powering connected
loads.
Battery SOC High: The maximum capacity AC300+B300 can be charged via
grid. Remaining capacity will be charged via solar panels, car, lead-acid battery
or second adapter only.
31
10.2.3. PV Priority UPS Mode
● PV Priority Mode: Recommended for areas with stable grid power. The
battery will be recharged mainly by PV for power savings.
● Note: In PV Priority Mode, AC300 can only be recharged via grid to 30%
capacity, and also discharge to 30% of the capacity (you can tweak it to
100% for full grid charging manually on touchscreen or App) as the "Reserved
capacity for PV charging". And rest of the capacity will be fully charged from
either solar power or 2 adaptors.
32
10.2.4. Customized UPS Mode
● Charge/Discharge time, and High/Low Battery SOC can be set in this UPS mode.
● Ability to disable the grid charging. The unit will not charge batteries from grid.
● Apart from Time Control UPS, the main switch of grid charging and time
mode settings are involved. The setting of "Time Setting" and "SOC Setting"
will take eect on both PV Priority Mode, and Time Control Mode.
