The Deye SUN-3K-G04P1-EU-AM1 is a 3kW single-phase on-grid solar inverter with one MPPT tracker, 97.3% maximum efficiency, and a 5-year warranty. It accepts up to 3.9kW of PV input at a maximum 550V, weighs 6.5 kg, and communicates over RS485/RS232.
3kW single-phase is the standard Indian home rating, and it is standard for a reason: it is the size the PM Surya Ghar rooftop subsidy is built around. If you are installing solar on a typical house, this is almost certainly the rating you are buying, and the subsidy is what makes the numbers work. Tell our team your consumption and we will show you the net cost after subsidy, not the sticker price.
An on grid solar system is the simplest configuration in solar and the shortest payback. No batteries, nothing to replace in five years, nothing to maintain. The inverter ties to your DISCOM connection, powers your house through the day, and exports the surplus through net metering so your meter runs backward the credit offsets your night and monsoon consumption. That is why a grid tied solar system remains the default for Indian homes, and why a 3kw on grid solar system is the most-installed configuration in the country.
The efficiency number is what to compare. At 97.3% maximum efficiency, this deye solar inverter converts nearly all the DC your panels produce into usable AC. That sounds abstract until you run it across fifteen years: every percentage point lost in conversion is generation you paid for and never received. When you compare inverters at the same rating, efficiency and warranty are the two specifications that actually separate them everything else is marketing.
Input headroom you can use. Max PV input is 3.9kW against a 3kW rating, which means you can slightly oversize your panel array. That is standard practice, since panels rarely hit rated output in real conditions a 3.9kW array on a 3kW inverter generates more across a year than a 3kW array does. The MPPT voltage range runs 70–500V with a rated input of 360V, maximum PV input voltage is 550V, and max operating input current is 20A with short-circuit tolerance to 30A. Your installer needs these to design the string layout; send them to our team and we will confirm the array matches before you order.
One MPPT, and what that means for your roof. A single tracker manages one string of panels. That is correct and cost-effective for a straightforward rooftop where all panels face one direction with consistent sun. If your roof faces two ways, or a water tank shades a section through the afternoon, a dual-MPPT inverter will generate more. Tell our team your roof layout and we will tell you honestly which you need a single MPPT on a split roof costs you generation every day for fifteen years, and that is not a saving.
Practical specifications. At 6.5 kg in a 280 x 310 x 184 mm cabinet, this mounts on a utility wall or an external wall without special provision. RS485/RS232 communication handles monitoring.
Sizing it correctly. A 3kW inverter suits a 3–3.9kW array, roughly 6 to 8 panels at 500W. Undersize the inverter and you clip generation on peak days. Oversize it and you have paid for headroom you never use. Tell our team your panel count, wattage and roof layout and we will confirm 3kW is right, or point you to the 4kW or 5kW.
SolarClue is India's managed solar marketplace. Our team confirms this inverter matches your panel array, your single-phase supply and your DISCOM's net metering requirements before you order, and we handle your PM Surya Ghar subsidy application end to end eligibility, paperwork, DISCOM coordination, payout. If you are working out which is the best on grid solar inverter in india for a home, compare this against Growatt on our platform; we will tell you which suits your roof, not which we are holding. You book with a token payment rather than the full amount upfront. Supply and installation are coordinated through verified partners, and we handle Deye warranty support afterwards.
