I am a DIY guy with this project - Two Multiplus II 48/5000/75-50 installed in parallel and connected to two 48V 280Ah Docan power Lithium batteries with Daren BMS (each) also in parallel. Three PV panel systems connected to three Victron smart Chargers. Victron Lynx distributer used for cable connections. All connected to my Cerbo GX MK2 for monitoring. The system is programmed with ESS with no feed-in tarif and with Victron energy meter vm-3p75ct installed close to main grid meter in single phase. A change over switch is installed near the grid meter as extra precaution between the grid and the solar energy system.
Your comments are welcome.
