Hi
I have a problem with the max charge on my new inverter. It seems to limit to 130 A (6600 watts) in charge mode (ESS) but will happily deliver 9500watts in inverter mode. The webpage Victron & Pylontech UP2500, US2000, US3000, US2000C, ...Victron Energy · https://www.victronenergy.com › live has a table in section 2 that suggests I should be able to achieve the full 8kW charge rate at 25 degree C.
My setup
8 x pylontech US5000 with 800Ah storage. During charge the allowed max charge rate from the BMS was 640Amps. It started reducing after 91% SOC.
1 x Quattro 10000 240V which is connected to a lynx distributor. The 95mm2 cable runs are extremely short 50cm. The batteries have 4 sets of cables connecting them in pairs so 4 cables that are specced for 120 Amps each. I'm looking to put 288 Amps through each and they are cool to the touch.
1 x Cerbo GX running the show.
All devices have the latest firmware as of this post apart from the Quattro which is at v500. The battery & room temperature are at 25 deg C though I started at 14 deg C.
I have been through all the settings and ESS and DCVV have charge limit disabled. The only setting I could find that might have some bearing on everything is if I look at the settings file using VEConfig. In the charger tab I have weak ac unticked. I am using grid on AC 1. The charge current is set to 140A. I am unable to set it any higher despite my battery system being more than capable of taking more. Lithium batteries are ticked. Battery type defaults to 'no corresponding type' after putting in the voltages/absorption time from the document referred to above.
Is there something obvious I have missed? I have been through every single page on the cerbo to make sure there is nothing that could be affecting the charge rate. How can I achieve the 8kW rate with the ESS enabled?
thanks
