10A PWM so­lar con­troller

Practical Boat Owner - - Solar Panels -

PrIce: £23 This is a sim­ple con­troller that gov­erns the max­i­mum volt­age go­ing into the bat­tery, but does not have the ef­fi­ciency of the PMMT unit. It does have many fea­tures, how­ever, in­clud­ing pro­tec­tion against re­verse po­lar­ity, over­charge, deep dis­charge and overnight drain back from bat­tery to panel. It does not have a dis­play, but can be con­nected to an MT50 re­mote screen, or via a Wi-Fi mod­ule to your phone, or an RJ45 to USB cable to your lap­top, al­low­ing you to mon­i­tor and al­ter a whole range of pa­ram­e­ters, in­clud­ing bat­tery type and cu­mu­la­tive charge and dis­charge to­tals. It works on 12V or 24V.
