Choosing a solar inverter takes more than comparing kW. Check single-phase or three-phase connection, grid voltage, AC power, DC/AC ratio, each MPPT range and current, string design, grid code and communications. For hybrid models, also verify the battery, BMS, firmware, metering and backup.
| Application | Main criteria | Critical checks |
|---|---|---|
| ApplicationResidential grid-connected PV | Main criteriaPhases, AC power, MPPT, start voltage, input current and monitoring. | Critical checksString Voc and Isc, minimum temperature, DC/AC ratio, protection and grid code. |
| ApplicationHybrid with battery | Main criteriaAll of the above plus battery range, charge/discharge power, metering and backup. | Critical checksDocumented compatibility between inverter, battery and BMS, firmware and critical loads. |
| ApplicationC&I and large rooftops | Main criteriaPower, multiple MPPTs, string current, operating efficiency, communications and control. | Critical checksAC board, DC/AC protection, grid, export, monitoring and environmental conditions. |
| ApplicationRevamping an existing plant | Main criteriaAdaptation to the existing PV array and AC connection without assuming a direct replacement. | Critical checksStrings, insulation, protection, transformer, communications, regulations and outage strategy. |
A hybrid manages a compatible battery and, depending on the architecture, backup. A grid inverter converts PV generation for consumption or export. Exact functions depend on the model and complete system.
Use PV array power and orientation, connection, grid limits, load profile, DC/AC ratio and temperature conditions. Do not select it only from total module nameplate power.
No. Check Voc, Isc, string current and count, MPPTs, AC connection, protection, communications, any transformer and grid requirements. Revamping requires a specific assessment.
No. DC compatibility requires documented matching of models, voltage, BMS and firmware. An AC-coupled battery may coexist electrically, but this does not mean direct DC-port compatibility or universal functional integration.
We help review the PV array, grid, MPPT, battery, communications and commissioning.
