-=== designing for MPPT ===
+There are some considerations when [[electrical:solar:mppt design|designing a system around an MPPT controller]].
-There are benefits from using [[electrical:solar:panels#panel_voltage|higher voltage panels]] that can be realized when a system is designed for an MPPT controller.  An MPPT controller can be the centerpiece of [[electrical:converter#diy_converters|a DIY converter]].
-MPPT controllers are most efficient when input voltage (Vpanel) is about 2x nominal battery voltage (Vbatt).  When Vpanel rises above 2x Vbatt more heat is generated when downconverting.((https://www.homepower.com/input-voltage-controller-efficiency))  At less than 2x the controller may not have enough "headroom" to work efficiently.
