Beyond the listing issues, there are also the NFPA 855 maximum energy
storage limitations to consider that battery manufacturers and distributors
are not considering in their marketing, leading consumers to conclusions

I powered a MidNite LSOB transmitter from a Classic AUX, though the

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.

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 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
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.

I second using the 48v to 12 v DC DC converter. I've had success with
that, and avoided the issues Jeremy mentioned.

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

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

The EG4s like the Sol Arks
A number of people have mentioned strict code compliance.
How are lead batteries dealing with this?
thanks

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

Jay - Despite the exceptions in NEC 480.3 and 706.5 for lead-acid not
