Part 4: Operation in Charger Mode

WARNING: Fire hazard

In this situation it is very important to check the electrolyte level and S.G. in each cell at least once per hour. The charger should be turned off and the batteries allowed to rest a few minutes to do this check as the electrolyte will be bubbling if the charger is active. If further equalization is needed the equalize cycle may be restarted.

5.During equalization, measure the S.G.

When all cells have an S.G. of approximately 1.265, terminate the charge by setting the CHARGER switch to DISABLE. As a safety feature, the PROsine will exit Equalize mode after a specified period (depending on battery type). If the S.G. is still rising just before the charger exits equalization, restart the process by requesting an equalization charge.

6.When equalization is finished, check the battery electrolyte level. Top up as necessary with distilled water only.

Operating Limits for Charger Operation

Output Current: The maximum output current for the PROsine is 100 amps. You can reduce the total output if you change the Battery Size setting on the Configure Battery menu (see page 4–12) or the maximum AC Breaker Size setting on the Configure PROsine— Basic menu (see page 4–7).

Input Voltage: The charger can operate over the range of 90–135Vac. This wide range allows the PROsine to deliver a maximum current to your batteries even when incoming AC voltage is less than ideal. A built-in surge protector protects the PROsine from surges and spikes on the AC power line.

Power Share

The PROsine shares power with AC loads. It senses pass-through current going to AC loads and subtracts this current from 80% of the breaker setting. The current that is left over is available for charging the batteries.

In Charge mode, the PROsine operates from a breaker-protected 120Vac circuit. Therefore the total power for AC loads and charger operation is limited to 80% of the breaker rating (80% is the regulatory maximum permitted for continuous loads). In this limited power environment, the PROsine gives priority to user- connected AC loads (pass-through current).

Example A 30 amp circuit breaker is allowed to have a 24 amp continuous load.

If you have AC loads of 15 amps, the PROsine will give priority to your loads and allow the charger to draw up to 9 amps AC.
