I have an MPPT-100 1 50; and a MPPT 150 1 35 controllers hooked to 5 solar panels (1500 watts) on my boat, charging 5 Duracell AGM batteries. I need the voltage to get to around 14.5 V before the controllers go into absorption. The MPPT 100 goes to float almost immediately, while the MPPT 150 stays in bulk (bulk setting is 14.56v) and absorption is set for 13.8v. Shouldn't both MPPT controllers continue in bulk until the voltage is 14.56?
Hi,
I have the same issue. I have a setup of solar panels sending >20V and <0.6A.
My app indicates battery on float at >13V. But battery does not charge at all. Its been more than 2 weeks now.
Seems to be an issue. Can someone help please?
What Fw versions are they both on please upgrade to the latest
and please send a screen picture of the setting using the Victron connect app for both units
Thanks
