Installation is an EasySolar 5000/48 with the MPPT upgraded to a SmartSolar 250/100, charging 2 x US3000A Pylontech batteries. Solar panels are 4 strings of 4 panels each (48V, 420Watt) giving Wp of ~6400W.
The Ve.Bus voltage increases when systems starts limiting the Solar input power to ~ 4500-5000W (the limiting level is ambient temperature dependent)
Is this a bug?
If not, what is the reason the bus voltage would go higher only while limiting is active?
