This page is the battery parameter setting page. As battery is an important part of the energy storage
system, the battery parameters need to be carefully confirmed whether they are consistent with the actual
situation.
Battery saturation: reduce the charging current in advance to prevent overcharge. If it is set to 2, the
charging current will be reduced when the floating charging voltage is - 0.2V.
Number of batteries: the number of battery in parallel. E.g. 2V / 200ah battery, 240 in series and 2 in
parallel, the number of groups should be 2.
Number of battery cells: the number of batteries in each string. E.g. 2V / 200ah battery, 240 in series and
2 in parallel, the number in each string should be 240.
Battery capacity: single unit battery capacity, unit: ah. If 2V / 200ah, 240 in series and 2 in parallel, the
capacity is 200ah.
Battery charging overcurrent protection: the maximum value of the total charging current of the
battery. HPS will protect if the actual charging current is greater than the protection value.
Battery discharge overcurrent protection: the maximum value of the total discharge current of the
battery. HPS will protect when the actual discharge current is greater than the protection value.
Floating charge voltage setting: the floating charge cell voltage value of the battery. When the cell
voltage reaches this set value, the charging current approaches 0A.
Battery undervoltage alarm: the cell voltage value when battery undervoltage alarm activates. When the
battery cell voltage reaches the undervoltage alarm point, it will stop discharging and switch to trickle
charging in grid connected state. Different processing will be made according to different modes in off grid
state. Please refer to "operation mode - off grid mode" in Chapter 3.5.
Battery undervoltage protection: the cell voltage value of battery undervoltage protection. When the
battery voltage reaches this set value due to discharge, HPS will stop for protection.
Battery over-voltage protection: the over-voltage cell voltage value of the battery. When the battery
voltage reaches this set value, HPS will protect and shut down.
Battery start voltage: Only when the HPS battery cell voltage gets higher than the start voltage, HPS can
start.
This page is the economic mode time period setting page, which only takes effect in economic mode. The
time period after 24 o'clock must be divided into two settings. For example, 20:00-6:00 is the valley period,
which needs to be set as 20:00-00:00, 00:00-6:00.
The page without instructions is factory preset parameter, please do not modify.
If the subsequent scheme changes, please modify the parameters under the guidance of
ATESS.
Allowed modification points: “BMS communication enable“, The enabling model: PBD350, this requires
the battery has a battery energy management system. When the battery is with BMS communication, please
set to 1; otherwise, set to 0.
2. Calibration parameters:
This page will be set according to the technical agreement before delivery
This page is the calibration value of sampling coefficient. If the sampling is not accurate, it can be
calibrated through this value. It is strictly forbidden for customers to calibrate this coefficient. If the sampling
is not accurate, it needs to contact professional personnel to operate.
