<div dir="ltr"><div><div><div><div><div>Hello Battlemesh,<br><br></div>A recent, sadly abortive, funding application had my mesh network partner and I scheming interesting things to do with a fully solar-powered mesh of WR703Ns. These lovely little guys have been described as having only 0.5W power consumption, i.e. 100mA at 5V.<br>
<br></div>Is anyone presently using WR703Ns under solar power? Would you have batteries, panels, and charge circuitry you'd like to recommend?<br><br></div>My own searching yielded these 6V 12Amp-hour AGM batteries:<br>

Neglecting whatever inefficiencies in the charge controller or the 6V > 5V regulation.<br>

So, it seems such a 12Ah battery could supply a WR703N for days continuously. This would presumably work well for instances where sunlight is scant (e.g. windows in urban environments, polar latitudes), but the battery is large and heavy, possibly overkill.<br>
