Dynamic Load Balancing (DLB)
WHAT IS DLB?
Dynamic Load Balancing (DLB) ensures your household appliances get priority access to power. Your EV or PHEV charges using what’s left—automatically adjusting to the maximum available current (up to 32 Amps, unless configured otherwise).
As your home’s power use fluctuates, DLB responds in real time—charging your vehicle as fast as safely possible, without overloading your main fuse. It keeps your appliances running, your circuits protected, and your EV charging smartly.
DLB technology protects the main fuse when members of the house are using PCs, water heating, heat pumps, oven, dishwasher, washing machine and more. Appliances can access the electricity when needed and you won’t need to worry about safety or overloading your circuit board.
EVs are bigger and more power-thirsty but there is no need to invest in an increased power supply for your home. With DLB your EV is able to charge at the power left over making 63 Amps an adequate amount for your needs and economical too.
SOLAR PV DLB
Three DLB modes for solar PV
1. The EV charger in the Pure PV (photovoltaic)/Solar mode will control its own charging current as much as possible, so that the actual input value of the grid current is as close as possible to 0A.
2. Hybrid Mode: The EV Charger will control its own charging current as much as possible in the range of DLB setting value. Some will be grid power and some will be solar – depends on the setting you choose.
Example:
Using the Z-Box App on your smartphone edit “Max Grid Current” input value to 10A. If the actual current value from grid to household power is 5A (<=10A), and the PV power generation current is 20A, then the total current of household power is 25A (5A+20A).
3. Full speed mode: The Solar DLB box will no longer limit the charging current of the EV charger, and the wall charger will use the maximum current supported for charging.
We recommend that you engage a registered and licensed electrician to check your household wiring.
