P.S.
This problem is the same for the controller power source.

Please help
You may use any battery charger designed for lead acid or gell cell batteries up to 6 amp charging current. There should be many types available for use at 220 volts. Be sure that if you attend any regionals in the US that you bring your 120 volt charger with you. The other alternative would be to purchase a step down transformer (220 to 120) so that you can use any accessory wired for US line voltage. There should be little effect on the charger or the OI power supply when running at 50Hz. You may have a little added heating or maybe some added ripple (line related noise in the DC output)
