No email or call from Richard today, despite numerous requests... looks like tomorrow I'm having a chat with a couple agencies....
How to Report Dangerous Products
Even when companies follow all the appropriate safety regulations, industry guidelines and common good sense, unsafe products still seem to find their way somehow […]www.consumersafety.org
It's a damn good thing you are cute!!!!As I found more info on the firmware I had that manifests this condition, I posted the prior post.
My original post was based on what I assumed at that time. And now it appears what I said then is wrong. So I guess I am back pedaling now on that warning.
When I received more of information on what was going on I shared it.
So yes, my warning is in error and was my bad.
My system did not manifest this condition when running the original firmware that came with the unit. It ran for months.
It was after I updated with firmware from the development branch that it was manifest. When that was manifest for failing, I jumped the gun
Again, my bad
He's the last of a dying breed... see my comments here:Cool you are one of the pioneers - thanks for sharing!
Which 240v inverter are you thinking of?This year I have produced 98% of my power from Feb to June
January was to pay for grid purchased due to heavy snow and cloud coverage in Dec when I couldn't produce much
The ONLY load I have that is on the grid is the 240v range/oven
when I upgrade to a 240v inverter then that will go away
the 15kw from EVTVWhich 240v inverter are you thinking of?
That’s what I figured, ?. Sig has an 18k with Tesla configs / profiles now, have you seen that? https://www.sigineer.com/product/18...-inverter-charger-120v-240v-110v-220v-230vac/the 15kw from EVTV
Sigineer 15kW 48v Inverter for Tesla Battery Modules
THE MOST POWERFUL 48Vdc INVERTER IN THE WORLD. Battery powered off-grid systems are quite popular and 48Vdc is the current voltage of preference. Unfortunately, most 48Vdc inverters are simply a poor match for Tesla Battery Modules. Why? The main problem is the Low Voltage Cutoff - the point of...store.evtv.me

I did see that BUT it has a higher idle draw of 250watts vs the the 210 watts of the 15kwThat’s what I figured, ?. Sig has an 18k with Tesla configs / profiles now, have you seen that? https://www.sigineer.com/product/18...-inverter-charger-120v-240v-110v-220v-230vac/
correct , NO backfeed to grid, it is meant for off grid use or rather as a dedicated circuit of consumptionDescription says "compliant to UL 1741"
Manual doesn't appear to describe backfeed to grid, anti-islanding, etc. Do you know what it does?
Page 22 mentions frequency-shift of SMA, Schneider, other GT PV inverters. It says the Signeer toggles between 60 Hz nd 62.5 Hz to let GT PV feed in or cut it off, while off-grid, and Signeer's inverter operates bidirectionally to to charge battery. Too bad they toggle instead of ramping frequency up/down.
18 kW of AC coupled battery inverter for $4k. But not sure if it lets GT PV backfeed grid through it.
"WARNING: The inverter is capable of charing batteries with PV AC power applied to its AC output when it is in DC to AC invert mode, but there is no over charge protection. Users must use a BMS or protect the battery from overcharing."
Well, maybe not quite.
And was that a Freudian slip they made?
BMS can indeed provide some protection against over charring ?"WARNING: The inverter is capable of charing batteries with PV AC power applied to its AC output when it is in DC to AC invert mode, but there is no over charge protection. Users must use a BMS or protect the battery from overcharing."
Well, maybe not quite.

Yup, without that, it's just a big heavy inverter like the rest of them...He was at least able to get them to put that profile into the inverter's flash
it is this last feature as to why I am going with it.
for others not that great an inverter with the newer tech out, like the EG4 inverters and batteries
