I’m doing something wrong and I’d appreciate some help.
I’ve got my four 48 volt SOK server rack batteries hooked together feeding a Victron lynx distributor (aka bus bar).
I have also attached a victron 150/35MPPT to the distributor.
My solar panels are three 300 watt panels in series at about 70 V and 9 A. The panels are covered with a thick cotton tarp but still reading 70 volts.
The Quattro is connected to the distributor but not turned on.
I inadvertently hooked up the panels before the batteries. The mppt gave me a battery over voltage fault.
I disconnected the battery (with a temporary blade fuse) and disconnected the solar by pulling the wire. [edit-the blade fuse feeds battery to the mppt]
When I tried to insert the 30 amp blade fuse, it gave quite a pop. I haven’t found the fuse to see if it is blown. It went flying (chuckle). The wires on the battery lines to the mppt and distributor bus bar are all about 52 volts.
What’s the correct procedure at this point?
I’m thinking I should:
-power down the batteries
- insert the 30 amp inline fuse
-power up the batteries so the mppt can adjust to 48 volt
-attach the wire from the panels to the mppt
-uncover the panels
I don’t know why there would’ve been an in rush current to the MPPT in my previous set up.
Any thoughts appreciated.
