If in range of service, you can use a Verizon MiFi device for wireless access
and a wireless bridge to connect a data collection device like a SMA webbox or
and Enphase Envoy to the wireless access point (the MiFi). The amount of data
transmitted will not come close to the data limits.

Hi Jay
I have never seen a battery enclosure explode, but I have seen individual
batteries explode, always in a multiple parallel string configuration (4
strings or more)
Kind regards

I have an inquiry about a portable, solar powered public address
system. Are these available ready made? Has anyone made one?
Thank you,

Hi Jay,
I have. 4 golf cart batteries were installed in a non vented compartment of an
RV...with other electronics like inverter, relays, solenoids, etc. I was about
500 feet away and heard an expolsion. When I arrived at the RV, the bay door
was mostly blown off the hinges. Needless to say
Jay,
I have had a solar charged 12v RV/marine battery explode inside a very large
work trailer, but found that the battery was bone dry which may have been
the real reason for the melt down and not a trailer full of gas as the only
damage was a totally exploded battery case. I was working inside
Here is another issue related to this thread.
Yes, you can build sealed battery boxes and add vent pipes, fans, whatever,
but battery terminals and battery cables installed in a confined box will
have far more problems with terminal corrosion due to more concentrated
forms of gasses and a mist
Wrenches,
Once again I am trying to size a grid tie w/battery system and I struggle a
little with the efficiencies of them.
With PV Watts (v.1), is changing the DC to AC derate an accurate method for
getting the output?
Thanks in advance!

I have always dealt with that situation by putting a 4 gig SD card in the slot
and collecting the data over long periods, then dumping when there is a
connection. The internal memory is really small, only enough for short term
data, but the card slot takes up to 4 gig cards, and can store years
Please use the 90% of the CEC or PTC rating of the PV module at most.
Among several systems that I monitor daily, I have an example 11.760kw (STC)
system that has a 500Ah battery bank and it peaks at 77-80% of the STC
rating each day.
Peak is defined as the top of the bell curve that forms
I have designed and built one and have used it for many years: 6 kWh (gross
battery storage), 24 Vdc and 120 Vac at 1 kW ea; 850 W STC PV modules. PV
rack on casters and BoS in 8 cu-ft box on casters as well. One off design.
It keeps on ticking while taking a licking.

Sound systems hate square wave and modified square wave, so unless you want to
listen to a ground hum and some other mid frequency square waves under your
broadcast, only use true sin wave inverters for that.

I consistently see 87% DC kWh to sold kWh with my Outback system.
(don't forget to also consider the usual STC to PTC derating)

ps i forgot to add i am using a bank of lead calcium wet cells which have a
much lower standby loss than lead antimony.
