DiVER.Wilssen - monitoring and logging

Beitrag von shure » Do 28. Jun 2012, 01:22

The Wireless Logging System for Sourcing ENergy - Controller is monitoring some or all grid parameters. Wilssen is the brain of a DiVER grid, Wilssen is recommended but not necessary for operation.

battery voltage of each battery (multiplexed) (2s1p, 3s1p, 3s2p, 3s4p etc)
battery bank voltage
l1 phase current (has got to be signed for bidirectional measurement)
l2 phase current (has got to be signed for bidirectional measurement)

over current protection via SSR shutdown.
under voltage protection

optional: digital ZVD (zero voltage diode) function via comparator+ISR at ADC or interrupt attached to a plain digital port pin. SSR could then be used as OC protection, UV protection and ZVD. :)

SSR module may be replaced with a MOSFET at low power ratings.

The integrated current sensor packages from Allegro are quite expensive. The following will be suitable for a <200A grid.
Bidirectional integrated hall effect current sensor:
ACS759 ±50A to 200A
ACS756 ±50A to 100A
