For off-grid systems a lot of our customers have used Victron Blue Solar, Rich Solar, Phocos and Morningstar charge controller brands.
For systems that power solar refrigerators and freezers especially, we do not recommend MidNite Solar or Renogy. That is not to say these two brands are bad, however, we have found a pattern with our solar refrigerator customers that have used these later 2 brands and have had issues.
For On-grid solar systems, it would really depend on what your solar system setup is. Outback is a good brand, but it can be expensive. Shop around a few solar installers for more options available on the market.
