Bij het aansluiten van de CTklemmen luistert het heel nauw welke ct-klem je op welke fase zet.
Dit had ik ook. Staat op zich wel in de handleiding, maar je leest er over heen.
Dus CT1 op fase 1
CT2 op fase 2
CT3 op fase 3
Dit loste voor mij het probleem op van de verkeerde waardes.
Of klem voor klem precies nalopen (werd gek van de kabels) of trial en error de ctklemmen per keer verwisselen in de meterkast. (steeds op de app kijken of de waardes wel kloppen
CT Golden Rules
Grid CT
• Only ONE Grid CT per phase (check for only one ~ symbol in Linked Devices Info).
• Located to ‘see’ ALL import and ALL export current (i.e. always upstream of any junction box).
• Arrow pointing in direction of import (e.g. towards consumer unit if on Live cable).
• Must be on the same phase as the Master myenergi device.
All other CTs
• Arrow should point towards the consumer unit.
3-Phase harvi CTs
• When using harvi in 3-phase mode, the CT inputs correspond to the phase number (e.g. CT1 = Phase 1).
CT can dos
✔ Can be wired to ANY myenergi device in the network.
✔ harvi can be used to make ANY CT wireless.
✔ Cable can be extended up to 100m (must use twisted-pair cable e.g. one pair of CAT5). Cable can be
shortened.
✔ Can be clipped around two or more conductors feeding appliances of the same type (e.g. two Live cables
from two inverters that are on the same phase).
✔ Can be in close proximity to other CTs.
✔ Wires can be swapped around in device to reverse the direction of the readings (e.g. change import to
export).
✔ Can be grouped with other CTs of the same type so that the power reading is summed (e.g. east and west
solar Generation).
✔ Can be used on the Neutral conductor in a single phase installation(direction of arrow or wires must be
reversed).
✔ Can be set to none in the zappi menu if you want to exclude the reading.
