2.7 Maintenance bypass
Upon failure of Energier Pro, the Maintenance Bypass, which is located in Smart Box, can be used
for the purpose of system maintenance. As a result, on one side, the Energier Pro can be safely
dismantled from the rest of SIES for further examining and repairing, and on another side, the loads
can be continually powered by available grid or generator.
Please refer to Chapter 5.5 for more details of maintenance bypass.
This operation might damage bi-directional inverter, and can ONLY be performed by
professional. The failure of inverter due to unauthorized operation is out of warranty.
2.8 Intelligent charging management
SIES coordinates the battery charging from two chargers (Battery charger of Energier Pro and Solar
Mate MPPT charge controller) and charges battery according to multiple parameters related with
battery. Energy generated from PV array will be prioritized power source and grid as supplement
one, as a result the charging current won’t exceed the limit.
2.9 AGS (Automatic Generator Start)
With the built-in AGS function, SIES can automatically start the generator once the predefined
conditions are met. The conditions can be battery voltage, power of loads and length of time. A
software for Windows system is provided to easily program the conditions of starting and stopping
generator.
2.10 Load management (programmable AC output)
AC outputs L2 and L3 are for smart load control and can be programmed to control the specific loads,
for example air conditioner, water heater, etc. The load control can be based on combination of
conditions such as load power, battery SoC, length of time, or accumulated energy consumption of
relevant load.
