I had asked them advice, as I am not knowledgeable in electrics, they guided me through no problem, they are down to earth, practical, efficient, human, just in reach..... and nice... what more..
Great source of all things solar.. Fast and efficient service...
Branded item at reasonable price, easily ordered online and delivered immediately. No more to say and I could not have asked for better service.
The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay: - if the charge disconnect output of the VE.Bus BMS is high, and - if it senses 13,7 V (resp. 27,4 V or 54,8 V) or more on its battery charger connection terminal, and - if it senses 2 V or more on its battery terminal (the Cyrix will remain open if not connect to the battery). The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free floating, signalling cell over voltage or cell over temperature. In general a cell over voltage alarm will reset shortly after charging has been stopped. The Cyrix will then reconnect the charger after a delay 3 seconds. After 2 attempts to reengage with 3 seconds delay, the delay increases to 10 minutes. Whenever battery voltage is less than 13,5 V (resp. 27 V or 54 V), the Cyrix will disengage with a delay of 1 hour. Note 1: In case of zero discharge current, or a small discharge current, the Cyrix will not disengage shortly after the charger has been switched off and/or disconnected, because battery voltage will remain higher than 13,5 V. Note 2: If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,7 V or more, the Cyrix will reengage, with 3 seconds delay
