Higher Yield
Power Factor 1.0
Achieve higher power output with a power factor of 1.0 (for 6KVA & 6KW models). This ensures the inverter operates normally at 100% load, unlike systems with a power factor of 0.8 which may stop working at 125% overload.
Diagram Description: Compares power factor 0.8 (inverter stops at 125% overload) with power factor 1.0 (inverter operates normally at 100% load). It also shows the relationship: 6KVA = 4.8KW and 6KVA = 6KW.
More Powerful PV Input
The SPF 6000 ES Plus offers a maximum 8KW PV output capability. When solar power is sufficient, it provides 6kW for loads, with the excess 2kW used for charging the battery.
Diagram Description (SPF 5000ES): Shows a solar panel input of 6000W, feeding into the inverter. The inverter outputs 5000W to the load and charges the battery with 1000W.
Diagram Description (SPF 6000ES Plus): Shows a solar panel input of 8000W, feeding into the inverter. The inverter outputs 6000W to the load and charges the battery with 2000W.
Higher PV Input Voltage and Current

Scalable & Flexible
Two AC Input Terminals
The ES Plus inverter features two AC input terminals with an integrated ATS device, capable of meeting multiple AC source input requirements. Standard ES inverters have only one AC input terminal, necessitating an additional ATS device when two AC sources are present. The ES Plus's dual input terminals allow simultaneous connection to two AC sources, reducing costs.
Diagram Description: Compares a general ES inverter requiring an external ATS device for dual AC sources with the ES Plus inverter, which has two direct AC input terminals, eliminating the need for an extra ATS.
Dual MPP Trackers
PV Module Installation: General ES inverters have a single MPP tracker, limiting PV module installation to a single orientation. The ES Plus inverter's dual MPPT design accommodates multi-orientation installation requirements.
Diagram Description: Contrasts PV installation for a single MPP tracker inverter (suitable for one roof orientation) with a dual MPP tracker inverter (suitable for multiple roof orientations).
Parallel Extension
The system supports parallel operation of up to 6 units, achieving a maximum system capacity of 36kW. It also supports three-phase system configuration, offering significant customer flexibility.
Diagram Description: Shows configurations for a three-phase parallel system with multiple inverters and a single-phase parallel system with multiple inverters.
CAN/RS485 Communication with Lithium Battery
The inverter includes a built-in BMS port supporting RS485 and CAN communication, facilitating easy connection to various lithium battery communication methods.
Diagram Description: Illustrates communication flow: ARK Battery and AXE Battery connect via CAN to the inverter's BMS port (RS485/CAN), which then communicates via RS485 with Hope Battery.
Work Without Battery Brings Full Flexibility
The new SUB mode enables the inverter to operate without a battery, utilizing solar and utility power for loads when solar power is insufficient. This feature helps reduce the initial investment cost of the system.
Diagram Description: Compares the ES and ES Plus series inverters, which can work without a battery, with older inverter versions that require a battery.
