Total System Cost: Notice that the first consideration, total system cost, is not the same as comparing the cost of the central inverter to the cost of the aggregate number of string inverters needed to handle the same production of electricity. Here are the primary pros and cons related to system cost:
Inverter Type |
Pros |
Cons |
Central Inverters |
Lower DC watt unit cost.Fewer component connections. | Higher installation cost. Higher DC wiring and combiner costs. Larger inverter pad footprint. |
String Inverters
|
Lower balance of systems costs. Lower ongoing maintenance costs. Simpler design and modularity; ideal for limited inverter pad spaces. |
Higher DC watt unit cost. More inverter connections. Requires more distributed space to mount inverters. |
Total Energy Production: The efficiency of string inverters versus central inverters is essentially a wash, string inverters often may be slightly more efficient, but the difference is often negligible. Other key inverter differentiations related to system production are set forth below:
Inverter Type |
Pros |
Cons |
Central Inverters |
Optimal for large systems where production is consistent across arrays.Proven field reliability. | Less optimal for systems with different array angles and/or orientations. |
String Inverters |
Modularity of string inverters is better for systems with different array angles and/or orientations.Fewer arrays are impacted with one inverter failure. |
Newer and less field-tested product. |

Q:What’s the solar inverter?
A:The solar inverter or PV inverter, is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.
Q:How many kinds of solar inverters can be divided into?
A:Solar inverters may be classified into three broad types:Stand-alone inverters, Grid-tie inverters,Hybrid solar inverters.
Q:What’s stand-alone solar inverters?
A:Stand-alone solar inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays.
Q:What’s grid-tie solar inverters?
A:Grid-tie solar inverters match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
Q:What’s hybrid solar inverters?
A:Intelligent hybrid solar inverters, manage photovoltaic array, battery storage and utility grid, which are all coupled directly to the unit. These modern all-in-one systems are usually highly versatile and can be used for grid-tie, stand-alone or backup applications but their primary function is self-consumption with the use of storage.
Q:What’s the different between inverter and solar inverter?
A:Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accept PV input, it more save power.
Q:What’s the solar pumping inverters?
A:Advanced solar pumping inverters convert DC voltage from the solar array into AC voltage to drive submersible pumps directly without the need for batteries or other energy storage devices. By utilizing MPPT (maximum power point tracking), solar pumping inverters regulate output frequency to control the speed of the pumps in order to save the pump motor from damage.
Q:How to choose the right inverter for your solar system, string inverter or central inverter?
A:The decision on whether to use a central inverter or string inverters needs to be made on a case-by-case basis taking into account primarily two elements: (1) total system cost (including space constraints) and (2) total energy production.
