Re: [RE-wrenches] Discover Xanbus SOC jumpy

Mac, I have a system that does this (or something similar) with all of the Insight data a few times every day. I'm pretty sure it is lost data resulting from communications drop outs. Internet to the site is via StarLink. If you are only seeing this on the SOC data there might be a problem

Re: [RE-wrenches] Ballasted ground mounts

A possibility for a smaller ballasted ground mount system is the Sunmodo Sunturf mount. It is difficult to find info on their website but you will find the Sunturf mount in the catalog and the configuration too. This mount can be installed on cast in place piers, earth screws, or concrete

First, I'll say that I agree with William's discussion. Let me add another way of thinking about this: Assume that, instead on two generators, your system is one backup generator and one utility company serving a commercial building. If the disconnect switch is your service connection, there

Re: [RE-wrenches] TPM Search

Jeremy, I think the Solar RacksWorks TPMs are virtually identical to the DPW TPMs. My go to TPM is General Specialties ; They are a solid design and I think they are easier to assemble. They also have UL listed TPMs but they have top mounting clamps,

Re: [RE-wrenches] Clamping CTs Around Live Conductors - White Paper References and/or Anecdotal Information Requested

Sam, As long as the CT leads are properly terminated, opening or closing the clamp-on CT core is nothing different that what a clamp-on ammeter is doing. Make a mistake and pull the leads out of the multimeter and you may have a high voltage arc. There are other problems with using a

Re: [RE-wrenches] Cleaning PV mods

Jason, This is the way thermal shock was explained to me. Thermal shock creates micro fractures in the glass. PV modules have tough tempered glass so one thermal shock event, or a few dozen events, is unlikely to cause a module to fracture; but eventually the glass gets to the last straw when

Re: [RE-wrenches] Inverter On/Off Switch use Outback FX

Mac, I think you've got an elegant solution to the problem. All you need is an inexpensive relay and to program the Aux output for loadshed. I believe shutting down the inverter with the remote on/off contacts is actually less stressful on the inverter than opening a relay or contactor on

Re: [RE-wrenches] Metering

If the inverter(s) provided energy production data, you would already have all the information you really need. Sounds like it must not. So, if you are looking for something that is relative inexpensive and reasonably accurate, but not revenue grade, you could use an Efergy True Power meter

Jason, Since the difference is not a consistent percentage, I'd look at the consumption meter settings. Make sure that the solar energy is accounted for correctly: either included or not included with the consumption metering. Kent Osterberg Blue Mountain Solar On 10/27/2022 8:59 AM,

I've seen a couple of those old Trace breakers with damaged set screw connectors. Its been a while back but I replaced one of the old Trace breakers with a Magnum breaker. Easy replacement, but you'll need to put lugs on the cables. That's a good improvement anyway. Kent Osterberg Blue
