Victron battery charge profile

[adrasto2006]

I just purchased and installed a victron 150/100. All of my previous controllers have had flooded battery profile. Not so with the V 150/100. You can define a custom profile, but before I create one, I thought i would ask the group for their recommended settings.

My battery bank is 6 6 volt Duracell 230 amp (690 ah total) flooded acid batteries in series/parallel. Each pair connecting to busbar Using equal distance cabling. I also have a victron 500 amp shunt and a battery temp sensor.

My panels are two 430 watt panels in parallel. WEUP WP430PM5-60SB solar panel:

Maximum Power (Pm): 430W

Voltage at Maximum Power (Vm): 35.63V

Current at Maximum Power (Im): 12.07A

Open Circuit Voltage (Voc): 43.28V

Short Circuit Current (Isc): 12.67A

Maximum System Voltage: 1500V (IEC)

Maximum Series Fuse Rating: 20A

Dimensions: 1723 × 1134 × 35 mm

Weight: 21 kg

Output Tolerance: 0 ~ +5W

Standard Test Condition (STC): 1000W/m², AM 1.5, 25°C

Operating Temperature: -40°C to +85°C

The battery charge specifications should come from the battery spec sheet.

I was thinking about picking up some of those panels - are you happy with them?

Rule of thumb: If in doubt, consult @sunshine_eggo

Is there a reason why you wire the panels in parallel vs series?

Only reason I can think of is if one points east and the other points west.

If they point the same direction you might gain a little efficiency if they are in series.

If you have an external temp sensor on the Smartshunt (recommend you get one), enable temperature compensation. -30mV/°C,

Check electrolyte level in all cells every 30 days. When filling the cells, use only distilled water. Purified water will do in a pinch.

If batteries are not fully charged, and you need to add distilled water, only add enough to ensure the plates are covered. Do not "top off" with distilled water until the battery has been fully charged and on float for 2 hours.

Check specific gravity in every cell every 30 days and log the data. Check only after batteries have been on float for at least 2 hours, and you have not added distilled water that day. Intake and expel electrolyte into the hydrometer 3 times before taking a reading. 1.265 is the target. 1.250 is the absolute minimum.

You will need to run equalization charges periodically - typically every 30-90 days depending on how stable the SG is. Generally speaking, if any cell is below 1.265 OR cells deviate by more than 0.030, equalization is warranted. Equalization should be terminated when SG stops rising or battery case exceeds 110°F.

If you fail to properly maintain your batteries in a manner representative of the above "best practices," your batteries will not last.

There's saying about flooded lead acid (FLA) batteries... the don't die, they are murdered.

You can get crazy life with FLA, but you must maintain them impeccably.
