FAQs
12V, 24V, 36V and 48V DC systems, with a voltage display range of 8V to 100V.
Yes - the Ah capacity must be set during initial installation as the monitor doesn't auto-detect it. It's also recommended to calibrate 0% (battery fully discharged) and 100% (battery fully charged) so the percentage reading is accurate.
The display shows the net current - charge current minus load.
It should be installed by a competent person familiar with DC electrical systems. Always disconnect the battery before wiring and fit an appropriately rated fuse close to the battery positive.
Press the SET button - this mutes the audible alarm and returns the monitor to normal operation.
Surface mount using the supplied bracket, or flush mount via a Ø55 mm hole cut in the mounting surface.
