I've been using the Hioki dc clamp meter just fine on 1500vdc circuits. I
only use it for DC, and it works fine.

Johns comment about the quality of internet connection, its quite important
for Optics to get good data into the database, especially if you are

its not optimal, but can work well if set up properly.

Hey Mac, Bergey Excel (10kw) and the Jacobs 3120 (20kw) are the only two
decent machines I can recommend. They are both not without their minor
issues, but all around, they work great as long as preventative maintenance
is done.

Have you measured the current of each string simultaneously while the issue
was happening? Have you verified correct polarity on each string?

Does the generator need to feed an inverter /charger input? In other words,
does it need to provide AC/60hz?
If it can be a DC genset (which is usually easier on the system) check out

Yup, id pre-drill and use an ez-out, or use a flaring tool as a small press

The midnite classic 250 can do this fine. Rectify the generator 110vac to
around 165vdc and feed into classic. Use Aux functions to start and stop
generator based on battery voltage or SOC %.

Loctite makes anti seize in aerosol cans. Not necessarily less messy but
certainly less tedious if all bolts are prepped on the ground and carried
up in a bucket for assembly.

In my experience, adding large electrolytic filter caps at the inverter
seems to help quite a bit with ac ripple issues and increases inverter
efficiency a bit as well.

Ive installed a few systems with these laminates years ago, but havent kept
up with performance much unfortunately. I have heard of the diodes going
bad (which are glued into the laminate along the sides). Maybe thats your
issue? Just speculating...

diameter to be hidden under the L-foot so UV (sun light) will never contact
