It looks like Linear has a real winner here. By combining peak load tracking and battery management functions in a single device, they’ve simplified design and manufacturing issues related to many off-grid solar applications. I especially like the fact that it can handle most emerging battery chemistries and a variety of battery pack configurations, including 1 to 4 Li-Ion / Polymer cells in series, 1 to 5 LiFePO₄ (Lithium Iron Phosphate) cells in series and sealed lead acid (SLA) batteries up to 18V. In fact, it may be just the thing I need for the small solar system I'm hoping to install on the remote lakeside cabin that Catherine's family has up in the Maine woods. I'm hoping to post a full review some time in the near future but for now click here to get more information from Linear's web site.

Linear Technology Says: The LT3652HV, is a higher voltage version of Linear’s LT3652 monolithic buck battery charger for modern battery chemistries. The LT3652HV offers a wider battery float voltage range than the LT3652 — up to 18V — and features the same input voltage regulation loop that controls charge current to hold the input voltage at a programmed level. The LT3652HV has the flexibility to charge many different battery configurations from various input supplies, and when it is connected to a solar panel, the input regulation loop maintains the panel at peak output power.
