Lead-acid batteries: For systems with lead-acid batteries, DVCC offers features such as a configurable system-wide charge current limit, where the GX device actively limits the inverter/charger if the solar chargers are already charging at full power, as well as Shared Temperature Sense (STS) and Shared Current Sense (SCS).

The MPPT in most of them will pull the greatest power they can from the solar array up to the maximum output current limit of the charge controller. When the max output current is reached or the battery is full and the charge controller needs to limit the output current, it must push the array voltage up so the the current is reduced.

The solar panel cannot deliver more than the rated current. Is more current is drawn, the output voltage will fall and thus current. Of course, the best method is to limit the current within the charger. If you try to limit the current externally that will interfere with the operation of the charge.

However, most solar charge controllers have built-in protection that will limit the charging current to max 50 Amps. Instead of limiting the solar array to 600W, you can use 800W as well. 800W/12V=66A. When over-paneling, the solar charge controller will limit the current it delivers to its maximum rated capacity.

You can also use this to decrease the power draw on purpose, i.e. if you''re charging off solar and don''t want to pull from the grid.

It is essential to observe the maximum current limits when charging AGM batteries. Exceeding these limits can lead to overheating and damage. Typically, AGM batteries can handle up to 10 to 15% of their Ah rating as maximum charging current. Solar charging: Solar charging provides an environmentally friendly option for AGM battery charging
Learn MoreThis refers to the maximum current required to charge the battery to full capacity. As a rule, battery manufacturers recommend a charge of 10% to 25% of the battery's capacity. So in the case of a 100Ah solar battery, the maximum charge current would be 10 – 25 amperes.
The amount of current a charge controller must hold will be decided based on the solar panel's total wattage output. For example, a 300-watt solar panel delivers 18 volts at 16.7 amperes of current under ideal conditions. Then your chosen charge controller must handle the current or power output at its minimal value.
The batteries say they have a maximum charging current of 37.5A, which I imagine i want to get as close to as possible in order to charge the battery as quickly as possible, but looking at descriptions of charge controllers it seems that they are rated more based on the amperage input (which i think would be 8A in my case - 400W/24V...).
What is the Maximum charge current from grid inverter to battery with a MultiPlus II 5Kva. We have 10Kw of lithium, 6.6Kwp solar connected to a fronius 5Kw grid inverter on AC out of a MultiPlus IIGX for offgrid use. We often see the fronius being ramped down and don't know why.

You can change to "use defined" and the limit will be gone. If you want to run your system in the "Li" communication mode, without the limit you will need S.S. to give you the firmware update.
