The heart of the Ray-MaxTM System, this is a state-of-the art 150 kW transformerless inverter approved for operation with DC string voltages up to 1000 V DC. Using advanced heat transfer techniques (no liquids), in a low profile cabinet (27” high), this inverter has total flexibility as to it’s placement in an array, on a roof, or in an equipment room. The inverter operates at full power up to 40 C, and the components are sealed against atmospheric contamination and moisture ingress when used outdoors. The inverter is certified to the UL 1741 / IEEE 1547 standard for both the US and Canada. Housed in a heavy gage steel cabinet, with a marine grade gloss white powder finish, this inverter stay’s cool in the hot sun.
The inverter is fully compliant with the UL 1741 / IEEE 1547 safety requirements, and when used in a stand – alone application (no master controller), will manage it’s MPPT and grid interconnect safety functions. Self protected against all forms of overheating, overcurrent, etc., this is a highly reliable design, with all active components mounted on a chassis that can be swapped out in 30 minutes if service is required over its lifetime.
When used in a Ray-MaxTM system, the inverter accepts commands from the master controller which controls when it is active (on-line) and whether it is the “master” for that day, or one of the slaves. In Master mode, the inverter manages the MPPT function for the entire array, communicating to the controller when it needs additional capacity from the other inverters to harvest the available energy.
The Ray-MaxTM inverter has a peak efficiency of 98 % (CEC listed as 95.5 % with a matching transformer) and includes an extended 20-year warranty.
After reviewing the few rare photos of other RV-4 inverted oil installations that I could find on the web, I finally came up with this. It's on the LEFT side of the firewall instead of the right side that is usually seen in other installations. The right side was a little bit "busy", with the heat muff hoses and the inverted vent tank located there. Hoses, fittings, and firesleeve to connect up this valve to the engine cost almost as much as the valve itself!
It took quite a few evenings of holding the valve in various positions to get the right combinations of vertical placement, access to fasteners, and hose clearance. Once I figured out where it had to be mounted, I bent and riveted the 3-piece bracket in one evening. I still need to place a doubler inside the firewall, as that stainless steel is pretty thin and I'm worried about developing cracks around the fasteners.

I'd love to introduce you INVERTED COMMAS! Some tote bags with original illustrations are available!
INVERTED COMMAS was founded in the fall of 2011, it is currently located in Florence, Italy.
The main purpose was to create a place to share my personal art and make it reach more and more people.
I work in very different areas, so I felt the need to find a vehicle to express myself. Again.
I chose "INVERTED COMMAS" because I'm the kind of person who says "in inverted commas" like a hundred times per day, obviously gesticulating too.

Digitally inverted from a new original unwaxed calotype negative
Pelegry dry calotype process with modified dr. Keith iodization (dropped free Iodine)
Canson Marker Layout Paper (batch 6-no 5)
Sensitized 3.3.12 according to Pelegry procedure (0,4 l sensitizer) with a preserving bath 2 weeks old (kept cool)
Exposed 4.3.12 on lightly overcast afternoon for 15 min at f/8 whole plate camera, no glass covering the paper negative.
Developed for 1,5 hr in 0,8% gallic acid, boosted with AgNO3 and acitic acid after 10 min
The rocks are pretty black.
Highlights showing well before development.
Inverted image of green leaves overexposed white sky. Hue/sat adjusted to get these colors. The tone effect is due to back light & shadows of leaves.
Very creepy house off of Hwy 120 West of Thermopolis. The front door is boarded up with almost looks like an inverted cross. We saw no No Trespassing signs, so we went on in via the back door. The back door was wide open, but there was a pool of blood (no, really) on the back stoop that we had to step over.
Ivy in the backyard. It transforms throughout the year from barren sticks covering the cinder block wall, to lush green leaves most of the summer, and now into a burst of color just before returning to the Earth as compost.
I purposely inverted the direction of this photo because it struck me as more interesting this way.
