Hi @SebastianLehmann Yes, The Multiplus is bi-directional and when connected the grid via ACIN and configured with ESS to feedin-in, the solar will first be supplying loads, then charge the battery and excess can be sent to the grid. Charger parameters are configured for bulk, absorbtion and float to avoid overcharging and the MPPT will reduce charging power as a result or provide the loads with whatever solar is available.
