Delta RPI- E5, 5kW Grid / 3.6kW Stand Alone, 2 MPPT Hybrid


Ideal for new Energy Storage installations



The Hybrid E5 energy storage system consists of a single phase 5kW hybrid inverter, an external
battery cabinet equipped with a high capacity 6 kWh Li-Ion battery, power meter and Smart Monitor.
The Hybrid E5 storage system has been designed to integrate seamlessly with the battery and
features dual MPPT, standalone function and a high charging efficiency of up to 97%. This is made
possible as the inverter can send DC electricity generated by the PV system directly to the battery,
without any additional power conversion steps or equipment required. The E5 inverter and battery
cabinet are compact and detach from each other, allowing for greater flexibility and simplified
installation. The power meter measures energy flow and displays the data on the Smart Monitor, which
can be used to control the system operation modes to maximise use of self-generated solar energy.

Product Benefit

Product Benefit

The E5 Hybrid Inverter is equipped with multipled pre-programed operational modes, which can be
adjusted to optimise the benefits to the home owner, according to their requirements. Some modes will activate automatically in certain conditions to maintain the system’s performance.

Peak Cut Mode
This setting helps reduce peak demand and subsequent cost from the grid provider by discharging batteries at a predefined ‘peak level’. When the home load exceeds the ‘peak level’ (set by the installer), the battery will discharge to assist the home power usage. This allows the stored energy to be used at times of the day when savings are greatest.

Self-Consumption Mode
This setting allows the owner to maximize the use of self-generated solar energy by storing the excess solar energy produced during the day for later use. In this mode the inverter will essentially act as a standard hybrid inverter with the added advantage of being able to programme different battery charge and discharge times for purchasing and exporting energy to the grid. When there is no PV power, the battery will supply home load until the available energy is depleted (night time).

Selling-First Mode
This function operates like a standard PV inverter with the additional benefit of a programmable battery to charge and discharge at specific times when purchasing and exporting power from the grid. The power generated by the PV array will feed-in to the home load and grid, unless time settings are programmed differently.

Without Battery Mode
This allows the E5 hybrid inverter to operate as a standard grid-connected inverter until the home owner is ready to add the battery unit. In the event of a battery fault, the system can also be programmed to supply localised loads directly from the available PV source (battery bypass).

Charge First Mode
This mode ensures that batteries are in a complete state of charge prior to PV power being fed into localised loads and the grid. This operation mode is particularly beneficial to systems in winter months, when daylight hours are reduced. It also solves any problems associated with local loads exceeding available solar PV, as batteries are charged first.

Discharge First Mode
This mode is where the battery continues to discharge until all the available energy is consumed. The PV power and battery power will be fed directly to the household loads and the grid.

Forced Charge Mode
In this mode, the hybrid inverter will force battery to charge from PV power and grid power until the battery's state of charge reaches 30%. This setting is especially useful when excessive battery use causes the state of charge to be lower than 0%.
