• Most popular choice for monitoring off-grid homes, RV’s or boats.
• All models show volts, battery charging and discharging amps, % full based on measured amp hours—and more
• Simple data logging focuses on identifying system problems. (TM-2025 and TM-2030)
• The latest model TM-2030 offers two choices which operate identically: the TM-2030-RV is easily fastened to a wall. The TM-2030-A fits into a “double gang box” and is easier to flush mount.
PentaMetric Battery Monitor System• More data than the TriMetric and more complex. Control with local LCD data display or use computer with optional internet access to data.
• Three amps channels to separately monitor battery amps, solar amps and an additional channel.
• Data logging: Periodic measurement of solar input, percentage full, volts, watts, amp-hours, charge-discharge efficiency factor and more.
• Relay control can be used to control a generator for charging.
• Works with the TM-2030 TriMetric monitor to provide precise charging in accordance with battery manufacturer recommendations.
• Returns a measured amount of amp hours—and also has a higher voltage, current regulated finish charge to avoid battery undercharge or overcharge.
• Connects to TM2030 monitor (see lower left) with common telephone cable to access all settings and readings.
• 30 Amps maximum solar current, 12 or 24V systems, PWM technology at lower complexity and cost than MPPT technology with approximately the same efficiency when using solar panels with voltage matched to batteries.
