GoodWe GW15K-SDT-30 G3 15kw On-Grid Solar Inverter (Three Phase) is a GoodWe on-grid solar inverter designed for converting photovoltaic DC power into grid-compatible AC power for on-site use or an approved grid connection. The GW15K-SDT-30 G3 designation identifies the product family associated with this unit.
Product overview
it is suitable for residential, agricultural, institutional, and light-commercial three-phase pv installations, subject to the model rating and grid connection. This is a grid-tied PV inverter. It converts DC electricity from solar modules into synchronized AC electricity for on-site loads and approved export to the utility network. During a normal grid outage, an on-grid inverter normally stops energizing the network for anti-islanding safety. Customers who need electricity during load shedding should select a compatible hybrid, battery, or microgrid architecture rather than assume that this product provides backup. The listed three-phase arrangement and 15 kW rating should be matched to the site’s utility connection, transformer, switchgear, and approved export limit. GoodWe’s portfolio includes residential and commercial grid-tied string families such as SDT G3 and higher-power HT-class platforms. For this GW15K-SDT-30 G3, the exact maximum DC power, maximum input voltage, operating voltage, MPPT count, string inputs, input current, output current, efficiency, power-factor range, surge protection, AFCI, communications, IP rating, cooling method, and grid certifications are model-specific. They must be taken from the current product datasheet. The designer should calculate cold open-circuit voltage, hot operating voltage, short-circuit current, parallel-string current, cable voltage drop, connector compatibility, and the effect of DC oversizing before approving the array. The inverter can suit residential, agricultural, institutional, and light-commercial three-phase pv installations, subject to the model rating and grid connection. Multiple MPPTs are valuable when separate roof sections have different orientations or shading patterns, but MPPT tracking cannot compensate for poor string design, dirty modules, damaged connectors, or heavy shade. For commercial products, the designer should also review voltage rise, reactive power, transformer capacity, protection coordination, and utility requirements. Installation requires DC isolators, AC breakers, surge protection, earthing, cable support, weather-appropriate mounting, clearances, and anti-islanding.
