<H2>Summary</H2>
<p>Since 2003 the bivy site at Steinbr&uuml;ckenh&ouml;hle (the stone bridge) has had a number of solar panels
and a car battery, which are mainly used for charging lamp battery packs, drill
and AA/AAA batteries (and phones). Much bigger flexi solar panels arrived in 2007

battery packs</a>, but also AA/AAA batteries and phones. Much bigger flexi solar panels arrived in 2007
and a second, larger, battery around the same time.</p>
<p>In 2018 two new PV panels were bought.

To charge the (now rarely-used) Bosch 24V drill batteries, the four solar panels should be connected together with two pairs of serially connected solar panels connected together in parallel. Crocodile clips can then be used to connect to the battery terminals. Note that the battery will not stop charging, and may damage the battery if left to over charge.
<H2>Putting the (Lead-acid) batteries away</H2>
Store the batteries full, this means that you should stop discharging the batteries a few days before they are to be put away to allow them to charge. Grease the battery terminals, and place the batteries where they will stay dry, do not cover with anything that may get soggy and short the battery (e.g. cardboard box).

<p>In 2019, as we had long feared, inexperienced and under-supervised cavers in a hurry dropped a lead-acid battery
several metres while putting it away. Fortunately no one was hurt. We now plan to try to run
power cabling in a much longer run to the PV panels and the bivvy so that the batteries need to bemoved as little as possible.
<H2>Thanks</H2>
On behalf on anyone using the system, thanks go to Earl Merson who provided most of the equipment, and more importantly carried a car battery up the hill. More thanks go to whoever carries it down again should it ever become knackered.
