Thanks again for the great tips! Hook controller to batteries first to ensure 12v system charging
. Unhook panel supply before controller in other direction.
I am starting to get the idea but my concerns mostly center on integration with existing system. Here is what I have:
- Battery bank: (2) 4D AGM house batteries, (1) 31 AGM Engine and genset start
- Magnum 3100 watt inverter/ 160 amp charger w/ remote panel and battery controller
- 40 amp battery charger (back-up)
- Link 10 battery monitor (secondary)
The primary system is the Magnum 3100 which replaced the Link 10/40 amp charger old system. However, when the Magnum was installed the electrician left the old system intact such that it can be selected should there be an issue with the Magnum. So there are side by side charging
systems which are supplied by either shore or generator power.
I'd like to add solar as a back-up should shore power
trip while I am away as well as to minimize generator dependency away from the slip. My concern is how to properly integrate the solar into the system so it works properly and no damage occurs to any components.
If the solar controller is connected to the battery bus while on shore power
I assume the solar controller will stop its own input as it senses charging voltage on the battery system from the dock
. If the dock
power is disconnected and the battery voltage drops below threshold, the solar would kick in due to the loss of shore power.
As for the generator, it is primarily to run air conditioning
. But you have to shut everything else off or it will be overloaded. But would it essentially be the same response for the solar controller to cut out solar supply when the generator is on line?
Is this an accurate understanding? Or is a switch needed to select which source is charging at a given time?
Thanks it you have made it this far!!!
