HD DVR dedicated inverter

Hooked up the Samlex 350 today. Damn fan runs all the time, and consequently the unit imparts vibration to the shelf.

From Amazon----"Unlike the PST series and other ones from Samlex, this fan is not temperature controlled, it is load controlled and the fan comes on regardless of what temperature it's actually running at
* Fan is quite noisy even at no load"

The big Sam is fine. Only issue is that it won't start my air. The old Pro did that just fine, but eventually burned up the pigtails doing it.

The GoPowers look like nice units.. and made up north of here.

I am replacing my large Xantrex with a GoPower.

I upgraded from a DTV HR24 to HR44 receiver and now have significantly less reboots due to AC power change over.

Pros: 3 minute reboot so much less interruption when it does reboot. Much faster menu/remote operations. 5 channel recording which provides more playback options when not on the satellites. High quality HD, TV is 1080 at home and 720 in the rig which is detected by the receiver via HDMI and automatically adjusts the receiver output. Can easily add mini Genie receivers. RF remote so the receiver is mounted vertically in the back of a cabinet.

Cons: SWM only which is not a con for me. High power consumption - have to keep that disk spinning: 240W + 72W for SWM, power off was slightly less. DTV said they use higher quality coax, compression connectors and barrel connectors due the much higher bandwidth required ie 5 HD channels at once on the coax. Lower quality coax may be OK especially for shorter distances so the HR44 may work in a rig with existing coax. Installation of multiple Genie receivers (bedroom/outside) should be easier since a coax is the only connection.

For a period of time I had both the HR24 and HR44 connected. I was quite surprised that the HR24 acted like a mini Genie in that I could watch all of the recorded programs on the HR44. I’ve discontinued the HR24 as we have no real need for a mini Genie and second TV.

Or a heavy duty 15a power strip off the inverter.

Thanks. I considered that after I did this. :)

Of course, I'm bypassing the breakers for the refer circuit.. I'll have to think about what I might do about that.

Could use a small breaker box for $20. Or a heavy duty 15a power strip off the inverter. I think if you have #12 wire I would just rely on inverter overload/shutdown during a short circuit.

Glad to hear you are back in business.

Nice work!

We're done.

Added a new 'tap' off the inverter side (top) of the 3pdt knife (xfer switch):



A small (orange) C-clamp makes an easy, strong holder for the new wire and connectors. It's clamped to a steel C- beam frame member. Really didn't want to drill that!

The only problem I see is the time lag in the transfer switch might drop out the Sat.

My Prosine's xfer switch was fast enough..IF.. I pulled the 30a plug instead of turning off the gens first.

I will use the now-empty Refer socket for the converter. Just wiring it up today, but it's getting hot again.

exactly..its not the "switching time", its the voltage drop on the generator output
when shore power shuts down, its instant
when you turn the generator off,
it whines down and the transfer switch doesn't switch until after the voltage has dropped too low for the DVR and sat to stay on

so use UPS
use dedicated inverter..no generator power
pull the plug
IF using installed generator, and installed inverter circuit
simply flip off circuit breaker in power panel or on generator,before turning off generator

i use a dedicated inverter, the electronics are always on the inverter, even if genset or shore power is available

OK thanks maybe I will be lucky then.
