In this video series (two videos in total) I will introduce you to a new DIY battery with Grade A cells from Hithium (Tezepower). The housing for the battery cells has a unique pressure device that clamps the Hithium cells with 300kg. There is also a new charger with a maximum charging power of 3,000 watts. The charger is controlled by a new Trucki board, the T2HG. The T2HG board controls the charging power of the charger to match the PV surplus. It communicates via WLAN or wired Ethernet (LAN) with an energy meter in the sub-distribution.
