Re: [RE-wrenches] Buck-Boost transformer to mitigate high voltage drop?

Howard- Any voltage drop at the house will be a function of current drawn by the house load. Shut off most loads and there will be minimal voltage drop.  If there was a low voltage issue now before solar is installed, there would be symptoms like florescent lights not working well. That's why they

Re: [RE-wrenches] Which commercial string inverters?

Wrenches We do lots of bigger systems and our inverter of choice has been SMA, we have seen many manufacturers either fail or be bought out, neither we have any control over but considering issues SMA has had the least of any. We have used fronius, AE, ABB, and satcon some filled with rain water,

[RE-wrenches] Which commercial string inverters?

Hello RE-Wrenches, I'm a long time recipient of great knowledge, experience and advice from this list, but I've been an infrequent poster. I'm curious about this list's opinion on the current status of the Commercial sized string inverter product options (from ~10kW to 80kW, 600 and 1000VDC fla

Re: [RE-wrenches] Buck-Boost transformer to mitigate high voltage drop?

My guess is that in your case the GTPV will just help alleviate the volt drop situation. I wouldn't start adding transformers, etc until you are having a problem. Put in the contract that this extra cost may be necessary for proper function, but I would keep it as a backup. Based on the numb

Re: [RE-wrenches] Buck-Boost transformer to mitigate high voltage drop?

Just a note: AIC has nothing to do with breaker trip amperage ratings or nuisance tripping, it has to do with the ability of the switchgear to interrupt very large fault currents for very short periods such as you would find close to a utility transformer with very low impedance in the event of se

[RE-wrenches] Outback radian issues

Hi all I was contacted by someone offsite about a 5 stack outback radian, grid connected that is having all sorts of problems. He's been in long contact with OB engineering but still no answers. If anyone has experience with such a critter, please let me know. Thanks Jay Peltz power.

Re: [RE-wrenches] Buck-Boost transformer to mitigate high voltage drop?

Chris: If you do provide transformers I think they are called step-up/step down. Buck/boost transformers I believe are to make adjustments to voltages. I have learned that you need to account for the current flow and direction. For one-way flow, the upstream transformer has a slightly differ

[RE-wrenches] Buck-Boost transformer to mitigate high voltage drop?

Answers to all: No - I did not measure voltage at the house. Right now, only an assumption of voltage drop based on my perception of what "typical" loads might be on this 150-amp service. I wasn't expecting to see such small wires for such a long run from transformer to house when I showed up t

Good day, I have a potential client that has an existing 1,000 foot run from the meter and transformer at the street to the home. This is 4/0 Al and quick calcs show the voltage drop at over 12%. He acknowledges that the wire is undersized to keep voltage at/about 240 volts (I have not measured
