Listeroid Engines / Re: compression/gasket/something = not firing up
« on: July 22, 2019, 02:30:45 PM »
tyssniffen,

The holes in the head gasket do not have to line up perfectly with those in the block/head.
As long as they are not blocked.
AND ... as long as your gasket has openings for ALL the holes in your block.
Some passages can be slightly restricted by a poorly made gasket, but passages must not be blocked by a gasket that does not have a hole corresponding to each passage in the block/head.

Well Glort ... I'm a lot less proficient at electronics than you, so I will be watching intently on your progress.
Hopefully you are willing to share your findings  ;)

Regardless of the gasket, if you had good compression when you cranked it over, the unit should have fired up.
Heating may have been a problem later if the water passages were blocked by an incorrect gasket. But with compression, the unit should have run.
You say you were running WVO before...
One issue that I and others have encountered when running wvo is a sticking throttle slider in the injector pump.
The WVO oxidizes while the engine is sitting for a while. I sets up like glue with a gummy film that prevents easy sliding of the throttle assembly. AND it can also block the fuel line. All depends on the quality of the wvo and how oxidized it is in the first place. Took me a long time to clean that out using zylene.
Check to see if that may be your reason for not running.
WVO is a great fuel but you have to be aware of how your unique collected oil reacts in your system.
I'm not saying that this is the problem with your machine, but it is possible, so check that out.
Break the fuel line at the injector and crank it over. See if there is fuel spitting from the injector line into a rag.
If not, work you way back. Break the connection between the fuel filter and the Injector Pump to see if fuel is flowing the the pump.

Thanks glort, I was not aware of the term "zero export".
I ran the numbers some time ago and the outcome is not very exciting.
However, I have these panels sitting on a shelf doing nothing at the moment.
This would be a "winter only" application with the panels almost in a vertical orientation and facing due south (for north American orientation).
The big problem is the cost of a "zero export" inverter rated at 3kw.
This system would NEVER pay for itself in 30 years when contributing only in winter.
(In summer the power usage is almost zero at this site so no need for solar).
I suppose the best application for spare panels is to heat a domestic hot water tank on a year round basis.
I can easily match the impedance of an element to the best efficiency point of my panels.
I also have an MPPT tracking converter which converts Panel power to a electric element sweet spot.
I bought one of these units a  year ago and plan to install it. I is designated for my hot water tank.

I think it is meant to achieve what you are working on.

I think you are right, the amount of energy I would produce trying to offset my space heater consumption would not be worth the effort.
Keep us posted on your water heating project. This is something where PV panels can really do well.
I have several water heating applications that would benefit from solar so if you come up with a good DIY solution for tracking PV power points it would be very interesting to see it.

22kw of panels ... wow! that's a good sized array you have there mate! That's more than my house uses per day. Which brings up the burning question of excess energy storage. We really only have two options. Store in batteries or store as heat.
Charging a small electric vehicle would be very feaseable with your system.

Everything else / Solar Inverter - Load sensing
« on: July 18, 2019, 02:44:22 PM »
I would like to be able to feed power from ten X 220w panels into my cabin electrical system to help offset demand from the grid powered electric baseboard heaters in winter. I am not interested in "net metering" or selling power back to the utility company. When all heaters are on at the same time the total load is 4kw.
That creates a mess of paperwork and meter changes which in the end will not be worth my effort.
I am wondering if anyone is aware of a grid tie inverter that modulates it's contribution to the home circuit according to the current entering the house main breaker panel from the utility.
The idea being that my solar panels would contribute to the loads when the heaters ( or other loads) are on, and scale back (or divert the AC to a dump load like a water heater) instead of back-feeding to the grid when there is low demand.
These type of inverters are readily available from non-approved (and probably poor quality) suppliers on Ebay.
They have a donut current sensor which clamps to the incoming grid wire at the breaker box which is wired back to the inverter for monitoring the incoming grid amperage. The unit throttles accordingly.
They also claim to have "island protection" which will shut down the inverter if grid power goes out. Thus preventing back feed during outages.

I am wondering if any North American brands are capable of output modulation or load diversion based on mains current draw.
Anyone else using solar to help reduce electrical loads without backfeeding the grid?.

Summary:
I want to offset the power used by my baseboard heaters without back feeding the grid

Looks like the unit is in good shape.
Congratulations.

CAVEAT:
Listeroids have soft crankshafts.
Do not lift by the flywheels.
Lifting straps should be looped around the bearing housings where the crankshaft exits the block.
People who say they lifted by the flywheels with no issues were just lucky.

+1 for Lapping.
Those components look good.
Give the valves a nice lapping before reassembly to ensure a good face-to-seat match and a fresh sealing surface.
Should be good for many more hours.

Listeroid Engines / Re: heads off the 6/1, should do gaskets, right?
« on: June 20, 2019, 05:40:17 PM »
tyssniffen,

When you re-assemble the head, consider spraying the head gasket on both sides with Permatex Copper Gasket coating.
Its adds additional sealing for the water passage ports.
Here's how I did mine ...

Brilliant marketing !
During power outages, everyone knows that the Pub has power.
They go there to get a meal and a Pint !  ;D
