Electricity saved during the night can be reclaimed during peak operating hours.

This system charges a battery at night when electricity costs are cheaper. It then redistributes this saved energy in the daytime, when electricity is more expensive. This allows cost savings for the budget conscious consumer.

Cost savings with embedded calendar functions.

The system is conveniently fitted with a scheduling function that allows the user to plan in advance. Combined with a PC, the system can set the charge/discharge cycle and the amount to charge/discharge. The system also has a function that checks the state of equipment, allowing for easy maintenance from anywhere in the world.

[Features]

1. Snubber (Surge Absorption Circuit)-less design.

Higher efficiency has been achieved by making the high-capacity inverter snubber-less. Higher reliability is also assured as we have reduced the number of moving parts. (The snubber circuit absorbs surges when the components in the main circuit function, protecting them from burnout.)

2. Reduced number of assembling processes for the main circuit block.

By making the inverter blocks into blocks, the number of steps in assembly have been reduced by 30%.

3. Scheduled operation by calendar function.

The installed calendar function allows the user to schedule operation of the system in advance.
