Hello Peter,
Is there good cell coverage or Internet access on the site? What
Inverter are you using?
Best,

We have sold an off grid system delivering 24 volts DC. The
application is “mission important”. We have built in a LVD and
alarm, but the client wants an "early warning" system based on
sending text message to a cell phone number. So we need to program a
LCD around 20% residual capacity (easier part) and a cell phone
interface. I know the PPA community has a solution: high-end comm
link and big bucks. Is there something simple and cheap that we can
implement?
