BATTERY CABLE CONNECTIONS

Up to 3 batteries are supported in parallel when connected to a single inverter, 4 batteries in parallel when connected to 2 inverters, or up to 5 batteries in parallel when connected to 3 inverters.

The maximum recommended number of paralleled 18kPV inverters is 6. If this approach is used, we recommend a ratio of 3 batteries per pack controlled by each 18kPV inverter. Separating packs is only recommended if each pack's average SOC is monitored over time and does not diverge by more than 10%. Common busbars are superior to separating battery packs but it may be difficult

Not perfect, but good enough for daily use
Style: Qi2 Charging Mount
Well made and very strong magnet. Make sure you tighten it completely or it will fall off. The tightening screws are not intuitive, but after some confusion you can figure it out. Works as intended and charging is as fast as your phone allows.

Fast charger
Style: Qi2 Charging Mount
Simple to install. Holds tightly and has enough adjustment flexibility to get your phone positioned the way you want it. Fast charger and mag holds tightly. Only downside is where to plug in the charging cord. But that would be a problem with any external charger.

charger works, not the adhesive on the ring.
Style: Qi2 Charging Mount
The metal ring adhesive was destroyed by the unit's heat in a few weeks. Do not buy it if you need the adhesive ring to hold the phone. The blinking light ring is annoying - why is it needed.
