Frequently Asked Questions
What is the primary distinction between the MultiPlus-II, MultiPlus, and MultiGrid?
The MultiPlus-II uniquely combines the functionalities of both the MultiPlus (inverter/charger) and the MultiGrid (grid-tie capabilities with anti-islanding), offering a single, integrated solution for complex power systems including grid-tied energy storage.
Can the MultiPlus-II be effectively integrated with a generator for power generation?
Yes, the MultiPlus-II can be integrated with generators. It can automatically start and stop the generator based on battery voltage and can utilize generator power to supplement its own output, especially during peak demand.
Explain the function of PowerAssist on the MultiPlus-II.
PowerAssist is a feature that allows the inverter/charger to draw additional current from the battery to momentarily augment the output of a weak shore or generator input. This prevents overload by adding inverter power to the available AC source power.
How does Dynamic ESS optimize energy consumption?
Dynamic ESS intelligently manages energy flow within an Energy Storage System, optimizing self-consumption by prioritizing the use of stored solar energy, discharging batteries when solar production is low, and managing grid feed-in based on user-defined parameters and real-time conditions.
Describe the UPS functionality of the MultiPlus-II.
The UPS function ensures that AC power remains uninterrupted during a grid outage. The MultiPlus-II switches to battery power in less than 20 milliseconds, a transfer time so fast that most electronic equipment, including computers, will not experience a reset.
