The 'charge current limit' (CCL) as shown in the parameters screen (and received from the BMS, by
the GX device, via DVCC) will be the ceiling, and the system will try its best not to exceed that (as
much as it can - it may spike under momentary peaking conditions).
This parameters page is also a good place to check that all batteries are connected and working
properly. The battery data sheet specifies the normal working conditions, e.g. the current limit per
cell. For example, If each battery is rated to 25A charge current, and the menu shows a 75A charge
current limit ( 75 / 25 = 3 ) means there are 3 Pylontech battery modules connected.
In off-grid systems, the inverter will prioritise running the load, and potentially exceed this Discharge
Current Limit. This could lead to the battery shutting down, and why it is important to follow the
minimum battery sizing guide.
In grid connected ESS systems, the inverter will do its best to respect the Discharge Current Limit and
use the grid to supplement the load if required.
Note that 'details' menu of the battery (e.g. Lowest and Highest cell voltages etc) is only supported
with recent Pylontech firmware.
The firmware requirements for the details menu is documented in the table below.
