Re: Amel is going lithium

Hi Scott,

To place the charger in the engineroom has some downsides:
- hunidity
- heat
- limited space so probably the charger is mounted sideways what lowers airflow.
- long wires

I customized widened the switch area and drilled ventilation holes to the alley.
I install 120mm thermocontrolled fans with heat alarms to blow fresh air into the cabinet.

The 120A5000W fits vertical.

The lifepo is smaller than batteries before with same capacity so i could install a new separation.

The starter batt is now behind the onan in the engine room.

No more dirty lead in the cabin. Hydrogen Should not be an issue as most other yachts place the starter batt around the engine room.

I guess this is a reminder that I still owe the group my writeup. :)

Oliver, how do you vent the compartment where you've installed the Victron 24/5000/120 inverter/charger? I mounted mine in the engine compartment (connected with the recommended 2x pair of 50mm2 wires - not 95mm2 as I previously mentioned) in the same location as the old Dolphin 100amp charger, with the same ventilation from outside as the original Amel setup. 

Even then, the charger/inverter gets damn hot especially when we are cooking and the induction, microwave and boiler are drawing tons of current. Or when it's charging at the full 120 amps.

Part of the reason I ask is that the electricians installed the Victron 150/35 MPPT in the same compartment where you installed your charger/inverter (where the main battery switches are) and I'm getting very high temperatures in that closed compartment after a full day's charging. If you've figured out a good cooling solution, I'd rather implement that than try to move my MPPT!

I was considering adding a little timer controlled 24v fan on the vent in the battery compartment and connecting the two compartments, but haven't for two reasons: (1) Amel kept the two compartments isolated. I am loathe to violate that as they probably did that for a reason (2) The fan is just another part to fail and I have enough things to keep up with already!
