How do I connect the Pylontech to the Schneider Insight Home or XANbus?
With the introduction of the Schneider Insight product family, Lithium Battery Systems with a BMS communication connect no longer directly to the XANbus but indirectly to the CANBus port on the Insight Home or Insight Facility. Check the installation manual of your battery system and make sure you use the correct wires that are carrying the communication of CAN H, CAN L and GND. For more information consult Frankensolar’s detailed TechTip about the integration of Pylontech batteries and BMS with the Schneider Conext equipment.
What Schneider product replaces the discontinued Schneider Display SCP?
Schneider Electric has no direct replacement product for the SCP display. It is recommended to use the new Schneider Insight Home or Insight Facility devices for online and offline systems.
The Schneider Insight hardware supports configuration via a smartphone or conveniently with a laptop and its browser via the integrated WIFI access-point of the Schneider Insight units.
Added advantages of this system is, that if internet service is available, system monitoring comes to the Insight Cloud comes with it and remote parameter adjustments are possible!
SMA SunnyBoy Fault Code 4301 or 8206 - Arc Fault/Electric Arc Detected
If this is the first time that the inverter is showing either Code 4301 or 8206, you can follow SMA suggestions to reset the detection by
tapping on the enclosure lid twice in quick succession. Here, the operation inhibition can only be reset if the event is showing in the display when you begin tapping.
The tap with your knuckles where the display board is located. This is where the ‘knock-sensor’ is located.
Can a Pylontech US3000C be used below the freezing point?
You might be able to discharge energy that is stored in the battery modules down to a lowest temperature of -20deg C. You can NOT recharge the battery until its core temperature is above 0deg C. We recommend proper insulation and access to a heat source to keep the batteries above 5deg C for best performance.
Can the Fronius Rapid Shutdown Box Quattro or Duo be used with a Fronius Symo 3phase inverter?
Yes, generally the Fronius Rapid Shutdown boxes can be used. However, the Quattro and Duo rapid shutdown boxes are only certified up to 600Vdc.
Stringing of the solar array will be affected and only 600Voc compatible designs are possible. This might affect the maximum output power and compatibility to specifically larger inverter power classes. We do not recommend this operation.
What is the difference between a Fronius Symo Advanced Lite and a Fronius Symo Lite inverter?
The Fronius Advanced inverters have a Sunspec Rapid Shutdown transmitter built in. The inverters can then be used with Sunspec compliant
Rapid Shutdown devices like the APsmart RSD-S.
What is the maximum solar PV amount that can be connected to a SMA SunnyIsland system?
For each watt of continuous AC output power, you can AC couple up to two watts of solar inverter capacity.
E.g. A split-phase system of two SunnyIslands has approximately 12kW cont. Therefore up to 24kWac of solar inverter capacity can be AC coupled.
This would be e.g. 4pcs SMA SunnyBoy SB6.0-1SP-US-41. You can also DC:AC oversize the inverter to accommodate a DC size higher than 24kW.
With a DC:AC ratio that is common and recommended for larger Off-Grid systems of approx. 1.5:1 you could go to ~36kWdc on the inital 2x SI6048.
How many SMA SunnyIslands do I need for a 120/240V split-phase system?
Each SMA SunnyIsland SI6048-US is providing one 120V phase. Together two SI6048 units create a true 120/240V system.
What communication methods can the SMA SunnyBoy be connected to the internet with?
The SMA SunnyBoys can be connected with its integrated WIFI or via one of the two Ethernet ports in the connection compartment.
What Rapid Shutdown System can be used with the SMA SunnyBoy inverters?
SMA SunnyBoy SBx.x-1SP-US-41 inverters have a Sunspec Rapid Shutdown RSD transmitter built in.
