Megawatt Inrush And Small Generators
In the interests of accuracy I have copied John Marles, comments verbatim and they appear below "Inrush is 50A/115VAC 50A/230VAC for a few milliseconds on the S-400 and S-350. Its controlled by due...

- Capacitor
- If It's not needed it is not needed
- If it is needed with an underpowered prime mover you'll know it right away
- Close the switch and the engine lugs and dies
- With capacitor enabled engine powers inrush but labors when button is released. Cap should stay in circuit
- Start versus run in this case is a matter of common sense
- Run caps are designed to stay in circuit
- Starting caps are not
- They are inexpensive
- But go through the rigamarole of getting a start cap but discover you really need as run cap as well. Most folks would blanch
- Using a cap should definitely not be standard practice like using a booster on a roof air
- I saved this until now: I have a 55uf run cap for use with the Hyperwatt
- Unless it is throttled back it definitely blows a 15 amp breaker if an additional load is placed like a combination of huge refrigerator and several fans
- Put the cap in circuit and the breaker does not blow
- But even a drawn-on 15-amp home circuit will not distort like a cheap generator sine wave distorts
- When my finances catches up to the month maybe November, I'll test hop this with a Harbor Freight 2-stroke generator. That will reveal a definition finding.
- If startup with a weak sister public power circuit causes a line voltage burp, doing so with a marginal generator may (?) be over-the-top
- Finally the BORG does indeed blow hotel breakers even using one charger
- I am forced to ramp potential charge rate to 0 then ramp up once the 680uf caps charge
