Small Dripping After Hot Water Tuneup -- Simple Fix


Small Water Noticed After Tuneup?

We try to seat the valve when we perform our service, but because there is water present in the process of the tuneup, we cannot determine whether any small weepage could still be present.....so we need to ask our customers to try the simple quick fix below if they suspect minor leakage.  
--------------------------------------------------------------------------------

Almost for sure, any signs of residual water the next day, on the floor, is simply related to the new Pressure and Temperature relief valve needing to be flipped a few time to properly “seat”.   The contact surfaces of the new valve just need to be seated, and you do this by opening the P&T valve using the silver handle on top of the valve.   
  
·        Open for say 5 seconds, and be aware that water will rush out the pipe which usually goes to the concrete floor and usually in back of the tank and it could be really HOT.   

·        Then Close, and open again.   

·        Repeat one more time.

This should stop the leakage.   It might be hard to tell right away, as usually the leakage is very slow.   

Another simple trick is to put a box fan on the area and dry it up.     If it stays wet, then probably a leak continues.     Repeat steps one more time, but at the end just pop the valve quickly with bursts of water going out.

If it is dry, and remains dry when the fan is removed, then the expected fix has worked.     

This is a one time event, once seated well, you shouldn’t have to do this again.

Don't Squander This Opportunity to Upgrade Your Old Microinverter System at Low Cost


Enphase, the best microinverter company on the planet, is making a spectacular offer, allowing "early adopters" to upgrade not just their microinverter, but also  the electrical cabling on the roof, and the monitoring device (the Envoy).

ORDER NOW, PAY in JAN or FEB!


 I have run through the system myself -- and so far it looks easy.    Enphase is also very responsive via email and phone, and I got 15 minutes with the program manager today.  

 Those customers (almost all) who have the M190, the M175, the M210, and the M215 know that there is a fair amount of inverter failures, and these can be costly to change, especially if they are being done one at a time.    We expect that of the earliest technologies, almost all the
inverters will fail over the life of the system, say 25 years.   

Bottom LINE -- Your labor costs to keep changing inverters over the years and decades is going to be higher than just doing this SPECIAL UPGRADE PACKAGE NOW.

Also, they will not charge your credit card until the product ships to you.    So to get past the holidays and all those expenses, simply direct them to not ship until late January 2019.    We plan on doing most of these conversions in Feb 2019.

----------------------------------------------------------------------------------------------------------
Enphase is throwing A LOT of "balance of system" items for FREE!

Let's take a medium large system of 28 panels and microinverters.   If you have to buy all the parts at list price it would look like this.

28 7IQ Microinverters @ $126 =    $3,528
32 Trunk Cable connectors @25 =    $800
3 End Terminators @ 15 =                  $45
4 Closure Caps @ 5 =                         $20
IQ Envoy and CTs =                           $750
---------------------------------------------------
Total                                                  $5143 Materials if bought at list price.

But Enphase, is, AMAZINGLY, charging just $67.5 for the inverters and throwing in all the other materials for free,  so the material cost is ONLY $1890 to upgrade a $30,000 system.   NOTE that you reuse the same panels, and we will quote labor, miscellaneous materials separately.     Note that except for the rails, this is pretty much a complete system rebuild at the rooftop. 

Honestly, we are only going to run this program for 6 weeks, so we will only be able to upgrade about half of the systems.      After that we need to get on to Preventive Maintenance Services for Solar Hot Water.  


----------------------------------------------------------------------------------------------------------

The customer (you) initiates the process and does the purchase of the reduced rate materials.  
List Pacific Energy Strategies LLC as your contractor, and everything will start flowing together.

Depending on your layout, and the particulars of your string design, and obstructions and gaps, we can coordinate with Enphase to make sure the right stuff is shipped directly to your address.    Not having enough trunk cable, or clsoure caps, or end terminators would make the installation day a nightmare.    We will bring extra parts of course, but it better to have the right stuff on site out of the gate.

How to Turn Off and Turn On A Sunny Boy System

There are 2 disconnects on a Sunny Boy system, and maybe a third disconnecting means at the
rooftop if the design called for it, but to just shut the system down, you can ignore any possible rooftop disconnect.

The order of shutting things down is critical, because the Sunnyboy Inverter monitors the incoming utility power for Voltage and Frequency.   

As a safety, if the Voltage and Frequency are out of Standards, the Sunny Boy will go into an "Error Mode" which can be very problematic to get out of.   I don't like it, but that is the way it is.

So, it's very do-able, just follow this, print it out is even better. 

So 2 aspects:   Shutdown and Re-Start.

On shutdown, you need to turn off the DC Disconnect first.   The Sunnyboy and it's brain run on DC power.   So if you shut down the DC power, the "brain" won't be concerned when the utility AC goes down later.  

SHUTDOWN:
Turn off the DC disconnect first, then
Turn off the AC disconnect

On startup, you need to do the opposite.   

STARTUP
Turn on the AC disconnect, then
Turn on the DC disconnect.

On startup, once you turn on the DC disconnect, the Sunnyboy will first check to make sure the AC from HECO is OK and within specs.   If the HECO power is not there....it will go into an error mode, that can be a big problem.   Then the upper light will start flashing green if all is OK so far.   

After a while, maybe 30 seconds, that light should turn solid green.   That's GOOD!   Anything else is bad, and you could retry the process, or may have to do a trouble call to PES.

Draining A Water Heater

Draining a Water Heater can take a long time.   So sometimes customers don't mind doing this simple step to allow their work to get done earlier in the day so they have a tank of piping hot water later that evening.

The most important thing is to make sure power to the heating element is turned off.   If the heating element is not covered in water, and turned on, it will fry in less than a second, guaranteed.

1) Turn off power at the circuit breaker or the disconnect.   Circuit breaker is easier and better. 
2) Turn off solar pump (usually mounted on tank) by unplugging it.    if it is a 240V pump, you can't unplug it, but turning the heater breaker off will remove it's power.   
3) close the 3/4" Ball Valve on the cold water supply to the pump.
4) Attach a hose to bottom drain and open the bottom valve with a screwdriver.
5) Lift the P&T relief Valve handle to a straight up position, this lets air into the tank, which is necessary for the water to exit.

It could take 30 to 60 minutes to drain, longer if the bottom is heavily sedimented.
