Hi, this is my first install of a Easysolar II GX. I am not sure if I am missing something in the configuration or if a hardware problem. I have an current transformer attached to grid tails, with no dc coupled solar(will add later.). I do have ac coupled solar on AC1 out. No real load on AC1. ESS assistant has been added and configured. I setup a scheduled charge and this also does not work. Any help would be appreciated. see configuration details below.

ESS (Energy Storage System) (size:1709)
*) System uses LiFePo4 with other type BMS
(This can be either a BMS connected via CAN bus or a BMS system in which the
batteries are protected from high/low cell voltages by external equipment.)
*) The battery capacity of the system is 100 Ah.
*) Sustain voltage 48.00 V.
*) Cut off voltage for a discharge current of:
0.005 C= 46.00 V
0.25 C= 46.00 V
0.7 C= 46.00 V
2 C= 46.00 V
*) Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*) The solar converter will start reducing its output power at 50.20 Hz.
Output power will be reduced to minimum when the frequency is 52.70 Hz.
The converter will disconnect when the frequency is higher than 53.00 Hz.
*) Total installed PV inverter power is 1500 Watts.
Total installed PV panel power is 1500 Watts.
*) Relevant VEConfigure settings:
- Battery capacity 100 Ah.
- PowerAssist unchecked
- Lithium batteries checked
- Dynamic current limiter unchecked
- Storage mode unchecked
Total size of all assistants including the required
(hidden) system assistants is: 1782
