I would challenge that inspector's assumption. It starts becoming
precedent if you don't. I have challenged many rulings, and have lived
to tell the tale. There's a process and you just politely go through
the process. Often just mentioning that I will challenge a particular
assumption
Jay - Despite the exceptions in NEC 480.3 and 706.5 for lead-acid not
needing to be Listed, and the maximum capacity exception for lead-acid in
IFC 1206.2.8.3, one of our local AHJs is now insisting that ALL residential

To this point I'm not aware of a lead battery that is compliant to 9540 or
1973...we are still trying to work out the kinks of these UL codes.
This what happens when people try to blanket fix a problem with one
technology and apply it across the board without a full understanding of

A number of people have mentioned strict code compliance.
How are lead batteries dealing with this?

Becareful with the EG4s and AGMs. Last I checked the EG4s couldn't be
properly programmed to charge at a high enough voltage to properly charge
some of the heavier plated AGM. Surrette and Full river AGMs need to be
charged at 58.8 temp compensated to -4mv/deg/c...
The EG4s like the Sol Arks
I used to be Lead AGM for Off-grid; I used the Pure Lead Thin Plate for an
install 4 years ago from AltE, and it is still working fine. I believe the
LiFe is the battery for off-grid and the trick is to find the correct BMS,

Chris;
I was definitely moving to the LFP camp for off grid for all the same
reasons you mentioned, but I've just had too much trouble, so I'm
heading back to lead acid for now. I missed the acid burned jeans, its
a "look".
Seriously, you mentioned customers coming back to a lead acid
I second using the 48v to 12 v DC DC converter. I've had success with
that, and avoided the issues Jeremy mentioned.

Hi Jeremy...
The Classic AUX outputs will put out about 13 volts and allow up to
about 200 mA maximum.
That might be enough to power the transmitter. That is only about 2.5
watts so might not work
directly.

Drake:
I prefer the UnigyII VRLA batteries. Full river 2 volt L-16s are pretty
good and they allow one string configuration in larger AH settings.
I agree that as features grow so does complexity. However there is no
substitute for good remote monitoring and control. I can understand much
Surrette and Full river AGM's Been berry berry good to me!

I fully agree that off grid solar has taken a major downturn. Once the
equipment became software based, the reliability dropped. Sure, there
are nice features available with these cyber enhanced systems, but the
cost in reliability makes being energy independent off the grid hard to
accomplish.
I powered a MidNite LSOB transmitter from a Classic AUX, though the
receivers didn't work with the Classic. The Classic is limited to 200ma
output and the Tigo and APS transmitters are rated at up to 800ma input, so
it might overload the Classic AUX output if they really do draw that much.

fortress is making improvements to their firmware for sure. The fortress envy 12 has generator warmup/cool down which is a really important feature IMO. The eg4 not. Nor does the Deye sol ark. JayOn Feb 16, 2024, at 8:48 PM, Chris Sparadeo via RE-wrenches wrote:Howie,The EG4 18K and the
