Buy replacement (unfortunately biannual) pump Rimini, which has a solar panel with built-in batteries and whose rust buttons after 1 year and a half).
CAUTION:
The battery pack is in the housing, but does not connect !!
It is therefore open (4 screws) and connect the box.
Otherwise the pump will operate with the solar panel.
Autonomy of about 2 hours after the batteries charged and without sun,
no cut (sometimes slight loss of power) in case of clouds.
Advantage in my opinion: the battery pack is replaceable by that of a remote control car and other gadget,
-1 Star for paper duplicate "before starting" which is German (admittedly with photos but anyway .... metttre has two copies so put one in French)
