Last year I got a couple of 24V/100Ah LiFePO4 batteries and the plan was to use them as power supply for 24 - 28V power amplifiers, and as extra capacity for my two older 12V/100Ah batteries.
The 12V system has been used with 3x 100W solar panels, and has supplied a few radios with power in the period from mid February until beginning of November last year. In the dark months I needed to help charging from the mains power, but now the same radios can be supplied with solar power again. It's likely that I will add more panels and an extra charge controller or two to the 12V system.
The total capacity of the 12V system is about 2.5kWh, and I have used it with my power hungry IC-9700 and a bit of other radios. It's possible that I will add a bigger 12V battery later, for a capacity of about 6kWh.
Enter the 24V system. The plan is to add the capacity, so I will have a total of about 7 (or 9) kWh at the radios, using a simple DC/DC charger from 24V to 14V, with constant voltage/current setting and some switching control.
Some more solar panels need be added to th 24V system. I have some already, but I need to get them mounted.
I have found some reasonably priced 450W panels, and I will likely add a few of those to the system.
I have a small and a larger power station(s) that will likely be added to the system. Also, I have some LiFePO4 cells, so I can make a 12V, 24V and possibly a 48V system for the workshop upstairs.
A tiny system for lights and audio in the bedroom is also under construction. Yes, there are many smaller and a few larger projects to build here, along with the radio experiments.
