SolaX Power X1-Hybrid-LV - Peak Shaving Valley Filling Mode (PSVF); Backup Mode

Introduction

■ Peak Shaving Vally Filling mode (PSVF)
■ Backup Mode
EPS
mode
The charging and discharging strategy of EMS battery:
This mode is suitable for using PCS as UPS or EPS. Using this mode alone
does not require the installation of an electric meter. The battery is always
fully charged when there is a power grid, so as to supply power to VIP load
after the power grid fails.
1. In this state, whether there is PV or not, the battery is fully charged rst,
and the battery does not discharge;
2. In this state, when there is a power grid, the battery is always fully
charged, which is suitable for using the energy storage system as backup
power supply equipment when the power grid is cut o󰀨.
3. In this state, electricity meter data is needed, and zero-export is enabled
e󰀨ectively.
4. In this state, if the battery power is lower than the minimum SOC value
(which can be set), the battery is forced to be charged to the reserved SOC.
Notes:
The PV power is superior to charging the battery, and the battery is only
charged (PV and power grid have the same priority to charge the battery).
* Battery charging power = maximum allowable charging power. If the PV
power is less than the maximum allowable charging power of the battery,
the remaining power will charge the battery from the power grid;
* If the PV power is greater than the maximum allowable charging power of
the battery, supply power to the load; if zero-expor is not enabled, when the
PV power is greater than [battery charging power value+load power], the PV
surplus power is fed into the power grid. If zero-export is enabled, PV limit
power = maximum battery charging power+load power.
Peak
shaving
and valley
lling
mode
The charging and discharging strategy of EMS battery:
This mode is suitable for the period when the electricity consumption of the
power grid is normal, the electricity price is normal and the online subsidy
is less. Choosing this mode alone does not need to install an electric meter,
but it needs to set a peak-o󰀨 period or a valley-lling period.
Notes:
* PV power > inverter rated power, battery charging power value = PV pow-
er-inverter rated power.
* PV power < inverter rated power, battery discharge power value = 0.
