What these specifications mean

Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter is listed with 12 published specifications from Gripsun, including AC voltage of 230/400 V, 3P+N+PE, voltage range of 200 V-1000 V, output power of 50000 W and output current of 83.3 A. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For an inverter, the figures that matter most are surge or peak rating, which covers the brief inrush of motors and compressors, maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect, the MPPT voltage window, which decides how many panels go in a string and peak and weighted (European/CEC) efficiency, typically 96–98.5%. It is the component that decides what a solar system can do: how much power you can draw at once, whether you can export to the grid, whether the system keeps running in a blackout, and how well the panels and battery are managed day to day.

What to check before ordering

The checks below apply to any inverter. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Match the battery communication protocol (CAN bus or RS485) between inverter and battery. Compatible voltages are not enough; without a supported protocol the battery management system and inverter cannot agree on charge limits.
Look at the warranty term and what it covers. Five years is the common baseline, ten is offered by stronger brands, and extensions are often cheaper bought with the unit than later.
Size the inverter against the loads you need to run simultaneously, not against the total wattage of every appliance in the building — a 5 kW inverter comfortably runs a fridge, fans, lights and a couple of ACs, but not all of them plus a water pump starting at the same time.
Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.

Where buyers lose money

Ignoring the ambient temperature rating. Inverters derate in heat, so a unit rated 5 kW at 25 °C may deliver noticeably less on a hot roof-adjacent wall at 45 °C.
Assuming any grid-tie inverter keeps the lights on during an outage. Standard on-grid units shut down for safety unless they have a dedicated backup or islanding output.
Overlooking the IP rating. An outdoor installation needs at least IP65; indoor-rated units mounted outside fail early.

Price and availability in Pakistan

Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter is listed at ₨ 520,000 (PKR) for Pakistan. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Gripsun locally before ordering.

Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter — frequently asked questions

How much does Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter cost?

Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter is listed at ₨ 520,000 (PKR) for Pakistan. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter?

We hold 12 published specifications for this inverter, including AC voltage 230/400 V, 3P+N+PE, voltage range 200 V-1000 V, output power 50000 W, output current 83.3 A and efficiency 98.5%. The full table is on this page, listed under model GRIN-07.

Who makes Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter?

Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter is a Gripsun product, listed under inverters with model reference GRIN-07. The Gripsun brand page lists the rest of its range so you can compare across the catalogue.

Is Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter right for my system?

That depends on what it has to connect to. For an inverter, check the MPPT voltage window, which decides how many panels go in a string, peak and weighted (European/CEC) efficiency, typically 96–98.5% and topology — on-grid, off-grid, hybrid or micro against the rest of your equipment before price enters the decision. Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.

Where can I buy Gripsun KSTAR G50KT 50kW Three-Phase On Grid Solar Inverter in Pakistan?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Pakistan — buying in-channel is what keeps the manufacturer's warranty valid.
