100% agree, I don't even have solar yet and I installed a TM-2030-RV monitor. The remote display is not a substitute for a good battery monitor. Also, not sure where your batteres are but the controller needs to be as close to the batteries as possible. This ensures maximum power gets to the batteries. Do yourself a favor and read Handy Bobs and Jack Mayers web sites.
