Hello... I have a wireless antenna running of DC power from Orion DC/DC
There is lead/acid battery, 2 small panels and AC source with IP65 Blue Smart charger.
Blue Smart charger and MPPT are connected in parallel to charge the lead/acid battery. The AC source is very unreliable, so that's the reason for the battery and 2 small panels.
The antenna uses about 50W continuously.
Right now I have the Blue Smart set to charger mode, but it looks like it's taking breaks between the charge cycles so the battery voltage sags between the cycles, especially in the night?
Is it better to set the IP65 Blue Smart charger to power supply mode? In this way, should I set it to float voltage or higher or lower and let the MPPT take care of the Absorption top-up in order to prevent overcharging? The IP65 Blue Smart charger will be plugged in 24/7 except the occasional black out.
Thanks for suggestions
