[RE-wrenches] Tiny House "all in one" hardware hunt

[Nick Lucchese]

I've had fairly good luck with the Phocos Anygrid 48v 6KW PSW series and
currently still have one on a mobile solar trailer. A 5 person construction
crew put it to the test to build a new home. A few random overloads but
otherwise it performed very well with a compressor, table and miter saws. I
have also installed one for a client but due to the site details I was
forced to install it in an area against my preference. The main shortcoming
is that it was in a greenhouse atrium connected to her house and it's
cooling fans run 24/7. No way to defeat them. For the majority of
installations it would have gone unnoticed but she was quite sensitive to
it's continuous hum so I was forced to replace it.

Technically the major weakness is it's inability to separate charge and
load current when programming for AC input. Also it can only be done in 10
amp increments. The bluetooth app is quite buggy as well. You learn to deal
with it but it's a major step back from what we're used to. The batteries
optional feature is unique but not practical for most applications. I've
purchased the Any-Bridge remote monitoring hardware but have yet to set it
up so no feedback there.

Have you looked into the Mango Power units? Their price came down
considerably a few months ago.

Good luck with your project, Nick
