the Tail current and/or the pre-set Absorption time has elapsed, the battery is fully charged. The Controller switches to the
Float stage. The Tail current is 1A for models 100/20 and smaller; and 2A for larger models. (When an automatic equalisation
is being performed this will also be reported as 'Absorption'.)
• Float: During this stage the float voltage is applied to the battery to maintain a fully-charged state. When the battery voltage
drops below float voltage during at least 1 minute, a new charge cycle will be triggered.
• Equalization: This is shown when 'Start equalization now' is pressed in the battery settings. The charger applies the
equalization voltage to the battery as long as the current level stays below 8% (Gel or AGM) or 25% (tubular plate) of the
bulk current.
* Menu items only available on MPPT models with load output (100/20 and smaller.)
• Load output on/off The function of the load output switch is to disconnect the load when the battery is low on power in order to
avoid damaging it. See the configuration section (4.2 below) for available load switching algorithms.
• Load current This shows the current being drawn by electronic devices, lights, fridge, etc.
Note that for the load output reading to be reliable, all loads must be wired directly to the load output ...including their negative
terminals. See manual or consult your installer for details.
Note that some loads (especially inverters) are best connected directly to the battery. In such cases the load output does not
show a reliable reading - the current drawn by the inverter, for example, will not be included. Consider adding a
monitor
which will measure all current going to - or being drawn from the battery, including loads connected directly to the battery
...not just the load output terminals of the charge controller.
Is my battery being charged?
The battery will be charged whenever the power available from the PV panels exceeds the power being drawn by the loads
(lights, fridge, inverter, etc.).
You can only tell if that is the case with Charge Controllers which have all loads connected to the load output terminals.
Remember: any loads connected directly to the battery can't be monitored by the Solar Charger.
4.4. History - Thirty-day graphic
(The fragmented square icon (top left) allows you to toggle between 'portrait' and 'landscape' screen presentations.)
A summary of activity for the last 30 days is presented graphically. Swipe the bar left or right to show any of the previous 30 days.
The daily log shows:
• Yield: The energy converted for that day.
• P max: The maximum power recorded during the day.
• V max: The highest voltage from the PV array during the day.
Clicking on any day/bar in the graph will expand the information to show charge-status times - both as hrs/m; and also as a
percentage of the 'charge' day. This graphic provides an at-a-glance representation of how much time your charger is spending in
each of three modes: Bulk / Absorption / Float.
