This page will be set according to the technical agreement before delivery
Device Information: This page shows the manufacturer, PBD serial number, hardware and
software version information, and the date of manufacturing, data in this page cannot be
changed.
Maintenance: the interface requires a password to login. It is for electrician and maintenance
personnel who are fully familiar with the structure and working principle of the system only, in
order to avoid damage to personal safety and the PBD, and please operate carefully.
Ÿ Enter the correct password to enter the submenu of "equipment maintenance". The submenu
includes: protection parameters, calibration parameters, power grid management, factory
settings. The default one is"protection parameters".
Upper and lower limit of output voltage: if the output voltage is higher than the upper limit or
lower than the lower limit, a fault will be reported and the operation will be stopped.
PV current upper limit, PV inductance current upper limit, output inductance current upper
limit, output current upper limit: when the current exceeds the set value, the corresponding
fault information will be reported, and the machine will stop running.
1. Protection parameters:
This page is set for the protection parameters of the machine. These parameters will be set
when the machine leaves the factory. It can only be changed after confirming with the professional
personnel.
Upper and lower limits of MPPT voltage: the selection range of PV voltage. The maximum open
circuit voltage of PV shall be less than the upper limit value, if the PV voltage is less than the lower
limit value, PV output will be stopped, and the PV panel shall be configured reasonably.
PV voltage upper limit: if the PV voltage is higher than the set value, the machine will report PV
overvoltage fault and cannot operate.
This page is set for the protection parameters of the machine. These parameters will be set
when the machine leaves the factory. It can only be changed after confirming with the professional
personnel.
Detection time: when the machine is started up, it takes some time to detect. This time is used to
determine whether the machine is soft started successfully. Later on, the contactor is closed, the
machine is started successfully and enters normal working state.
Upper limit of output power: the upper limit value of the output power of the machine, which is
set by percentage. The maximum output power is the set upper limit value.
PV starting voltage: the minimum voltage to be traced by MPPT.
PV starting power: if PV power is less than this power, restart MPPT for tracking.
Battery charging current: When charging normally, the charging current will reach this setting
value.
SOC upper and lower limit: when the charge reaches SOC upper limit, the battery stops charging;
when the discharge reaches SOC lower limit, the battery stops discharging. (when SOC judgment is
needed, it shall be indicated on the technical agreement)
5.6.1 单机系统接线
注意：PBD250配置光伏和电池时，需注意前后级压差，PBD250为一级升压电路，光伏配置的
开路电压需要比电池最低放电点要小，保证前级电压不会大于后级电压。PBD350为二级降压电
路，光伏最低电压>电池最高电压，电池最低电压>输出最高电压；尽量保证前级电压大于后级电
压。
