Whole house LumenCache install - Eastern Colorado

Post by lpott6 »

As a follow up to my introduction, here is the 1st post and summary of the LumenCache system that is installed in our Colorado home. I have included a few photos, more to come.

As I stated in the intro, energy efficiency was a key requirement for an off-grid home. Our solar system consists of 28 315w solar panels, 2 charge controllers, an AC/DC inverter and 24 6v lead acid storage batteries. There are 3 banks of 8 batteries in series totaling 48v and the banks are then in parallel. There is also a 14kw propane generator that runs automatically when the sun doesn’t shine. The system produces between 30 and 40 kwhs per day and the house consumes between 22 and 26 kwhs per day.

The LumenCache system components are divided into 3 locations in the house to minimize the wire runs to lights. Each light fixture and keypad is homerun wired to one of the 3 control locations.

Here is a brief summary of the installed equipment:

5 Enclosures with 13 PDMs
Accessory Power Regulators on each PDM
98 recessed ceiling lights
20 gimbal recessed lights
15 converted light fixtures with 42 filament LED bulbs
22 outdoor fixtures with filament LED bulbs
46 Wall TouchPads, 35 – 6 button, 2 – 4 button, 5 – 3 button and 4 – 2 button
4 Occupancy Sensors, 2 Wall, 2 Ceiling

Now for some pictures.

With the new L2-CC drivers, the silver 48-24V DC/DC are not needed. The L2-CCB were slightly more efficient but the Boost topology of the CCB is not as flexible as the boost/buck of the new CC drivers. The CCU are buck drivers with 95% efficiency. Ideal for 48V solar battery supply. The new socket bulbs are also 20-60V input, so no need for the 48/24V step down unless you have E12 candelabra bulbs. We could not squeeze the 20-60V driver inside so they are 20-40V (24V)
