Features of PRO KIT
1. Expansion Power Port
2 & 3. 24V-/24V+ M6 Port
This set of terminals is used for connecting the external 24V lead-acid battery or 24V lithium iron
phosphate battery to expand the capacity of R600 PRO. Please make sure the positive and negative
terminals are connected with the external battery correctly, otherwise the PRO KIT might be damaged.
This port is used for connecting the R600 PRO and PRO KIT with the expansion power cable. The firmware
of PRO KIT can be upgraded when connected to R600 PRO . When connecting with the external battery, the
maximum current and output are 8A (charging) and 750W (discharging) respectively.

24V External Battery Installation
3. Remove the expansion power port cover of the R600 PRO as shown in the figure and connect it to
the expansion power cable, then connect the cable to the expansion power port of the PRO KIT.
Please follow the steps below for installation.
Ensure that the external battery is correctly
connected with PRO KIT. Make sure the R600
PRO is turned o before connecting the R600
PRO and PRO KIT. Otherwise, PRO KIT will be
damaged.
1. Remove the two expansion port screws on the
lead-acid battery as shown in the figure ①. Then
connect the black OT terminal cable to the black
negative terminal, and red OT terminal cable to
the red positive terminal.
2. Unscrew the two expansion port screws of the
PRO KIT as shown in the figure ②, then connect
the black OT terminal cable to the black
negativeterminal and the red OT terminal cable
to the redpositive terminal. Make sure that the
black one is connected first, and then connect
the red one.

The default charging voltage of the
device is 26-27V. Under this setting,
thebattery will not be fully charged.
Users will need to select the battery
type and fill in the under-voltage value,
over-voltage value and max capacity on
the APP manually before use. If two
pieces of 12V are connected in series, for
example, two sets of 12V lead-acid
batteries with following specifications:
Highest charging voltage:13.6V
Lowest discharging voltage:10.5V
Capacity: 200Ah
Then when you connect the two
batteries in series, the specifications to
fill in the APP will be:
-Over-voltage value: 27.2V
-Under-voltage value: 21V
-Maximum capacity: 200Ah

Warranty Card
* Note:
1. PRO KIT will manage and reserve some capacity of the lead-acid batteries to ensure that it will not be
damaged. The reserved capacity percentage could be adjusted on APP. The default setting will be 30% or
higher.
2. It is recommended to use a lead-acid battery 200Ah, discharge rate > 0.3C, and the battery voltage can
still reach up to 20V under 900W load.A 100Ah cell may only be able to discharge 20% of its capacity
depending on the load. Small loads can release more capacity.
3. If you use the 24V lithium iron phosphate battery, make sure the battery has its own BMS to ensure that
its cells will not be overcharged or overdischarged.
4. If the voltage of the solar panel is higher than the voltage of the external battery, PRO KIT cannot be
charged through solar power. Users will need to charge the units by the AC input port of R600 PRO.
5. The temperature protection will be triggered if the battery voltage is too low and after long-term heavy
load discharge. Please place it in a well-ventilated place and after temperature protection, and wait for the
product to cool down to use it again.
