We had two good customer calls this morning, then I tackled 3 electrical projects that I’ve been equipped to complete, but have not been able to fit them in.
Over a relatively short period of time, this gadget will tell me exactly what the Amp-Hours consumption is for our biggest consuming DC appliance when on the hook. This will help finalize the battery storage requirements.
Also shown above is a separate volt meter to show me, at a glance, what the voltages are for the house and starting battery banks.
Solar Controllers are not like multi-bank chargers. They only charge ONE bank. So if you want to occasionally charge two banks a DC to DC charger is commonly used. But those are “one-way” devices. They assume one bank is ALWAYS going to be the one charging the other. Contraire mon Frere! There may be times I want the starter bank to get a boost from the house, and on cloudy days underway with the alternator running, we may want the house to get a boost from the starter bank! This switch enables me to control it either way.
These are great additions to our boat’s operation that I have wanted for a long time. Finally, these projects are DONE! And they enhance to current use of solar and planning our next steps with that system.

What is the Remote Battery Switch for? I couldn’t quite catch it from the post.

It enables me to remotely join the two main banks together, e.g. for solar to charge BOTH for a time. Or to get help from the house bank to start the engine. Etc. Since both are wet cells lead acid, same chemistry, it is OK for short periods. DC to DC chargers are a more sophisticated technology, are usually only “one way”. This relay can h Ed lo me manually move curr Ed nt in either way.
