Bogart Engineeing has two models of their TM-2030 battery monitor. The TM-2030-A does not include a case, so it may be flush mounted into the wall, or mounted in a double gang electrical box. The TM-2030-RV has its own case that can be surface mounted. Both models have datalogging capabilities for troubleshooting and monitoring the health of your off grid solar system.
