Simply Unbeatable | More Power in Less Space

The SmartSolar 150|45 is designed to accept solar panel (PV) input up to 650W at 12V, 1300W at 24V, 1950W at 36V or 2600W at 48V and has a rated charge current of 45A.


However, you should note both the open circuit voltage (Voc) and the short circuit current (Isc) of your combined solar panels and ensure this does not exceed the maximum input of the MPPT charge controller.  For the 150|45 the maximum PV open circuit voltage (Voc) is 145V and the maximum PV short circuit current (Isc) is 50A.  If you are unsure let us help you size the correct MPPT controller.


* Remember when wiring solar panels in series: voltage increases and amps stays the same & when wiring in parallel: voltage stays the same and amps increases


Auto-selects 12/24/48V on the output.  The charge controller once connected will automatically recognise your battery bank voltage. (sotware tool required to select 36V)


Bluetooth Monitoring built-in.  Remotely control and monitor the extensive features of your SmartSolar MPPT charge controller with built-in bluetooth by pairing it with your smartphone or tablet via the VictronConnect app.  (Bluetooth dongle not required)

SunPower 170W E-flex solar panels

So now I generally

don't bother hooking

up to shore power!

Thanks for all the help in planning my solar project for my boat. The two 170W flexible panels fit well on my Bimini and now I generally don't bother hooking up to shore power.  Although I haven’t had any long trips since my installation I have done a few day trips. And even with fridge, radio, plotters, autopilot and occasional radar it seems that these panels are keeping up with my usage. I did add some stiffener material to the back of the panels and attached the panels with zippers and they have survived a few 30 knot days and one night with winds gusting well over 55 knots. No damage at all and no signs of flexing problems. 

The advice and service has been great.  Thanks again.

high efficiency flexible solar panels

It made my project

work, thank you

Lyall and Katie are so knowledgeable.  I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough. The SunPower® Maxeon Gen III cells are compact and simply kick out more Volts/Current than all the others on the market today.   And by using the SunPower® panel, everything was smooth and efficient.  I love my new 170W 29V 5.83A panel!!  It made my project work.   Thanks Lyall for all your knowledge in making this work.

Terrific customer service, patient, always responsive

The process of researching a solar solution for my Beneteau 41 was simplified & clearly understood once I discovered Sun Powered Yachts.  Terrific customer service, patient, always responsive with guidance and products that just work. Being a novice at setting up a solar system, I had many questions along the way, and the team at Sun Powered Yachts were always there to answers my questions and provide support.
