what are Technical Architecture of Solis 60-75 Three phase energy storage inverter?

 

1. Hybrid Power Conversion Engine​

The dual-loop MPPT algorithm of the inverter adjusts to the changing input from solar energy, achieving 99% or more efficiency across a 200-850V DC input range. The three-phase output of the inverter is designed for 400V AC grids, making it ideal for industrial applications and high-demand uses.
Key Advantages:

Retail: Reduces grid-drawn energy reliance in a hybrid application by 40% while cutting your electricity bill.

Wholesale: A plug and play design greatly simplifies system design for battery storage (LiFePO4 / lead acid).

2. Grid Interaction & Safety Protocols​

With IEEE 1547-2018 compliance, the inverter can autonomously manage grid volatility of frequency/voltage deviations. With its built-in AFCI (Arc Fault Circuit Interrupter)​ and Type II surge protection, fire risk is lessened for both residential and commercial installations.
Certifications:
CE, IEC 62109-1 (safety), UL 1741 SA (anti-islanding)

RoHS compliance for eco-friendly material use

 


Battery Management & Energy Storage

 

H9a01e925228e4d7e89b27832488a5731p
The Solis 60-75 Three phase energy storage inverter has dual-port battery connectivity​ (AC/DC backup), allowing for grid-tied charging and battery discharge simultaneously. Adaptive BMS​ allow for LiFePO4 batteries to make it last longer, while charging can be temperature-compensated to optimize the charging cycles by extending the usable time by 30%.
Functional Highlights:
Peak shaving: Store surplus solar energy during low-tariff periods, reducing energy costs by 18–25% annually.

UPS-grade switchover: Seamless transition (<10ms) to battery power during outages, ideal for data centers and hospitals.


Intelligent Monitoring & Scalability

 

1. SolisCloud Platform

Real-time monitoring provides Data on several Performance Metrics (i.e. Yield, Efficiency) and communicates and alerts users of Predictive Maintenance. Data will be viewable by both Mobile and Web interfaces for Remote Diagnostics and Firmware Updates.

2. Parallel Operation
Up to 6 inverters can run in parallel for deployments of scalable systems and support systems of 100kW+ with a single control logic.
