Samlex Solar 900-RC Remote Control for SEC Chargers Consider choosing a Samlex charger that accepts this remote, if the following reasons are important to you:--in addition to allowing you to turn the charger ON and OFF from a distance of up to 10 meters (33 feet)--its LEDs will continuously inform you even in darkness which of the 3 stages of charging the unit is currently in a) Bulk b) Overcharge/Absorption c) FloatWhy would you want to know the stage of charging?The reason is that, if the charger never gets to the Stage 3 Float stage, it means something is awry, which in turn means that your batteries will never become fully charged.The following are four of the Samlex chargers that currently accept the 900-RC remote.Note that these are also four of the Samlex chargers that include a temperature sensor for your batteries, so that the charger’s DC output can be adjusted according to the extent that they are above or below the standard temp of 77F/25C (if a charger cannot compensate for the temp of the batteries, then they may end up over- or under-charged)--SEC-1250UL (12VDC/50A max output/AC input uses regular household grounded outlet that can handle 120V@60Hz up to 15A*--SEC-1280UL (12VDC/80A max output/AC input requires special grounded outlet that can handle 120VAC@60Hz up to 20A**--SEC-2425UL (24VDC/25A max output)***--SEC-2440UL (24VDC/40A max output)*****Maximum recommended Ah of your battery bank: 500**Maximum recommended Ah of your battery bank: 800***Maximum recommended Ah of your battery bank: 250****Maximum recommended Ah of your battery bank: 400The FIRST IMAGE depicts from left to right a) Remote Switch (B00HHRVKYO )for my Samlex SEC-1250UL charger (B00H8N9AKS ) b) Inverter Remote (B004RCQRZO) for my Samlex SAM-2000-12 MSW inverter (B004RCWYT2 ) c) MT-50 remote monitor (B00SW1ZP2W ) for my HQST 40A solar charge controller (B01B2938BU). The Remote Switch LEDs indicate that the image was made during Stage 2 of charging, which for AGM batteries is a continuous output of 14.4V; the Inverter Remote confirms my battery bank is being fully charged but that the inverter’s Output is only on standby (Fan icon is OFF)*****; the MT-50 monitor is confirming 14.4V, which confirms the SEC-1250UL is at Stage 2 of charging.The reason you want to know the stage of charging is that, if the charger never gets to a Stage 3 Float stage, it means something is awry, which in turn means that your batteries will never become fully charged.*****According to Samlex America, when the inverter is on standby the current draw is so small that it does not count as a load, which means no need to adjust the DIP switches to 2-stage charging, which bypasses stage 2. In the SECOND IMAGE, the green LED of the Remote Switch for the charger does confirm that Stage 3 was attained despite the Inverter Remote drawing power from the SAM-2000-12 inverter. The MT-50 depicts the following:--no power is coming from the solar panels (moon icon)--the voltage of my battery bank during the Stage 3 Float stage has dropped from 14.4 during Stage 2 to a fully-charged condition of 13.4V at the current internal temp of my battery bank--0.0A are currently, during the Float stage, being inputted into my battery bank--there is no load on my bank (fluorescent light icon shows 0.0V/0.0A being consumed).

The Samlex 900 RC is the perfect companion for your Samlex battery charger. It does what a remote control is supposed to do. It allows you to mount your battery charger one place and control it' s operation from a more convenient location.
