HI
I apologize for my spelling, English is not my native language
I want to make a backup for my small aquaponics system. I collected 18650 cells and I am testing them at the moment. I have a question please and would like some help, please
I have been using a computer UPS with a 35ah SLA for backup, its been working great but I would like to use solar and 18650 cells with the ups and trough the SLA out. I drew a simple picture of how I think it might work
The ups will be on power, and it will charge the battery up to 13.6 volt, too much for the lithium pack hence the dc to dc set to 12.3volt. The diode in the middle is to protect the dc to dc, I am not sure it will like power flowing through the wrong way, the diode on the side is to protect the battery being charged to 13.6volt but it will open the flow from the battery to the ups once the power goes out
Must include a solar charger?
Or how else can I have the ups function without using the ups?
