Hello, people of this thread, New member here, and i realize this thread is almost a year old by now. I'm having similar issues that keepsake is having with is generator not qualifying. I am gonna paste what i just emailed off to schneider electric, as it should give the most clarity on what my issues are and what i have tried
- I have two XWPro 6848 inverters, two MPPT60 150 Solar Charge Controllers, one Conext Gateway with an SCP display, and one XWAGS. This off-grid unit was installed in 2019. This past month a lithium ion battery got installed and took place of the lead acid batteries that were previously installed. All components have been upgraded to the newest firmware Schneider Electric has released (inverter: 2.04.00bn29).
- My generator worked fine at charging the lead acid batteries. After the lithium ion battery install and the firmware upgrades and settings changed so the lithium battery is charged and monitored properly from the MPPT Charge controllers and the XWPRO inverters. My generator will not "qualify" and charge the battery through the inverters. (I have no faults/warnings showing from the BMS or the inverters, it simply won't qualify for any length of time.)
- With XWPRO 6848, AC2 voltage limits set to the default settings the generator will qualify and connect for 2-3 seconds, then disconnect, it will try to reconnect after 40s approximately and it will repeat this cycle for 5 tries at least, (i usually turn off the generator by then). When i connect and turn an area fan/heater (1500 watts) to the generators 120 outlet, it will then connect to the inverters for approximately 20-30 seconds then disconnect, it will repeat this cycle about 3 times, after this it will reconnect but only for 5 seconds approximately and repeat this cycle.
- With XWPRO, AC2 voltage settings 'widened' so there is more voltage and frequency range on the high and low side to give a better chance of the genset staying connected, i tried to get the generator to qualify with the area heater on (this is plugged into the generator outlet directly), and it did qualify and connect for approximately 50 seconds and then it disconnected and it behaved the same way it did before. Without the area fan/heater it still would only qualify/connect for 5 or less seconds then disconnect.
- My Hz out the generator is sitting at 60 give or take 2 Hz depending on my experimentation with the generator speed. AC2 L1 volts averages 122, AC2 L2 averages 120 volts when the generator is not qualified/connected.
- When it is qualified/connected, my values were (on average) 3147 watts, 58 Hz, AC2 L1 117 volts, AC2 L2 130.4 V, AC2 L1 active current -12A, AC2 L2 active current -11.3A, AC2 active current -12.5A, AC2 voltage 247.4 V.
- Some more background, my LED Christmas lights would flicker when the generator is running, it did before when i had the lead acid batteries and the generator was running. When it is qualified/connected currently the LED lights flicker as well.
- My generator is a 1.3L isuzu diesel engine with a 8KW pancake generator, model: 332CSA5211.
- Any suggestions on what i should do in order to get the generator to qualify/connect to the inverters so it can properly charge the batteries?
