[RE-wrenches] Portable power station for surge loads

[William Miller]

Friends:



A long-time client has an ADU 755 conduit feet from the main house.  They
started off-grid but they are now grid connected.



In 1999 we pulled a 120 volt feeder of #1 aluminum to the ADU.  This
provides about 10 amps at 5% voltage drop.



This client wants to abandon a propane cook-top in the ADU in favor of an
induction cook-top (indoor air pollution as a consideration).  A sample two
burner induction cook-top is 1800 watts--too much power draw for this
feeder.



I was wondering if a portable power station rated at enough power to run
the induction cook-top might solve this problem.  The 10 amp power feed can
charge the power station at (hopefully) an acceptable amperage over an
extended time period and the power station can provide enough surge power
to run the cook-top intermittently.



I see the Bluetti AC500, for example, can be adjusted to draw no more than
10 amps when plugged into AC.  Unfortunately this charge rate, when running
at the full 10 amps, allows little overhead for other loads.  I presume
this 10 amps draw is only 10 amps when the internal battery is fully
discharged.  Maybe other units can charge at a lower rate.



Have any of you tried this?  Any input is appreciated.



William
