A complete, rational design of distributed power generation systems, need to have the power storage function, the energy storage capability. As distributed generation gap, leading to its input on the grid is not uniform, a tremendous impact when large-scale distributed generation connected to the grid when the input is not balanced interested in grid (grid to protect the stable and reliablepower supply. distributed generation systems with the requirements of storage through its own storage to stabilize itself (or nearest) generation of electricity peak load shifting the wrong valley phenomenon. distributed PV development in Europe, Germany and other countries with fast have been aware of this problem, and substantial measures to encourage distributed generation system with storage function, electricity storage has become the third pillar of distributed generation. 

Solid Dulwich has taken the lead in the global launch of the bi-directional the inverter energy storage products, one end connected to the grid, a termination storage batteries (lithium batteries, lead-acid batteries can support a variety of forms of battery) 

With access to millions of households distributed generation systems (such as Australia, have 100 million households deployment of photovoltaic power plants on its roof), greatly enhance the monitoring requirements of the PV system.Because the majority of users are non-professional users, unlike traditional power plants (with professional engineers) for maintenance. Objectively requires the installation or system vendors (such as buy solar panels) to develop a strong monitoring system to support the deployment of large-scale distributed power plant. Advanced monitoring system to support distributed generation at least the following functions: 

Solid the Dulwich global monitoring system, to support the monitoring of the Internet and 3G networks, users in any corner of the globe can through a computer or mobile phone and other smart intelligent terminal of the power plant monitoring, and cloud data storage. 

Distributed systems management, including "self-management" and "management" function. The "self-management" is a system by the management system of the inverter, monitoring data generation, storage, analysis, upgrades, and optimization. "Management" side of the point of departure from the grid, the grid to accept large-scale distributed power generation system, from the perspective of unified power grid scheduling requirements of distributed power generation system to accept a unified scheduling. 

Germany the implementation of 2012EEG standard, requires distributed generation systems unconditional acceptance of the grid scheduling in grid overload, the grid can be unified to send commands, distributed generation system derating to 60%, 30%, and even allowed to directly Stop input grid. Solid Dulwich its full range of PV inverters with this "management" capability, and full compliance with the latest requirements of the German EEG 2012 new energy regulations, by connecting with PM + Solar-Log connected to the grid, have become rare so that the strength of the inverter company. 

Favorable policies, frequently, distributed generation domestic industry both rejoice in the good news, a profound understanding of the future market will pay more attention to the economic benefits of the power plant, the low bidder. "Era will be the end, the performance will breakthrough price, become a major focus of contention. PV inverter to convert the direct current generated by photovoltaic modules into alternating current and fed into the grid, the inverter efficiency (decision) by the circuit design, key components, Production, power quality, storage systems, monitoring systems, and management capabilities advantage more and more owners attention. 

The efficiency of the inverter determines the power generation efficiency of the system, the conversion efficiency of the inverter and MPPT efficiency is a measure of the core indicators of the PV inverter; the harmonic processing power inverter and power quality of the power plant was positively correlated with trends, whether we can provide safe, reliable, efficient, high-quality energy output, a key measure of the grid-connected wind controller technical indicators; 

The storage capacity of the inverter for distributed systems to expand the range of applications to provide intelligent control, power storage for a long time, long battery life, storage inverter, touted by the market. Inverter monitoring, management ability is a necessary condition for the deployment of large-scale distributed systems, reflects an important indicator of the capacity of the inverter large-scale applications. 

The above indicators are indispensable. In the future, the competitiveness of enterprises in the inverter, not just a single generation product competitiveness, but to construct the competitiveness of the entire plant system. Solid Dulwich tightly around the five pillars of distributed power generation system from a forward-looking approach, breakthrough price performance in achieving world-class design, function, performance, quality, maintenance, on the basis of the level of service, competitive Price, occupied the commanding heights of the market.
