I'm trying to set my charging parameters for my setup. I have 4 - 100 Watt panels, 2000 Watt Pure Sine Wave Inverter, 20 Amp DC-DC Charger, 2 - 100 Ah SOK batteries, and this EPEVER as my MPPT. I went into the MT50 and changed the battery type to USER and was able to change everything except three parameters. The problems I have are as follows:
1. SOK said they want the Boost Charge Voltage to be 14.6 but the MPPT manual says it has to be equal to the Equalize Charging Voltage which SOK wants to be 14.4.
2. The MPPT manual says the Low Voltage Reconnect has to be greater than the Low Voltage Disconnect and SOK wants the Low Voltage Reconnect to be 10 while the Low Voltage Disconnect should be 11.
3. The Under Voltage Reconnect Voltage stays at 11.6 and won't go to SOK's requirements of 11.5. This is because the Under Voltage Reconnect Voltage has to be greater than the Under Voltage Warning and SOK says both need to be 11.5.
Below are the charging parameters directly given from SOK (I am putting a * next to the parameter for each issue, so for example - the charging parameters for issue 1 will each have one * next to it, Issue two will have two ** and Issue 3 will have *** next to them):
Over Voltage Disconnect 14.7 V
Charging Limit Voltage 14.6 V
Over Voltage Reconnect 14.6 V
*Equalize Charging Voltage shut off or 14.4 V
*Boost Charging Voltage 14.6 V
Float Charging Voltage 13.6 V
Boost Reconnect 13.3 V
**Low Voltage Reconnect 10
***Under Voltage Warning Reconnect Voltage 11.5
***Under Voltage Warning 11.5
**Low Voltage Disconnect 11.0
Discharging Limit Voltage 10.5
Equalize Duration 0
Boost Duration 180 minutes
