What these specifications mean
Solis 12KW On Grid Solar Inverter is listed with 6 published specifications from Solis, including depth of 219 mm, height of 563 mm, phase of Three-Phase and type of On Grid Solar Inverter. 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.
Choosing an inverter: the checks that matter
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.
- Confirm the inverter is approved by your local utility or distribution network before you buy if you intend to export power — grid connection depends on certified anti-islanding and local grid-code compliance, not on the inverter's specifications alone.
- 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.
What people get wrong
- 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
No price is published for Solis 12KW On Grid Solar Inverter in Pakistan at the moment. Pricing on solar equipment moves with supply and exchange rates, and some distributors quote only on request — the specifications above are still directly comparable against alternatives that do list a price.
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 Solis locally before ordering.
Solis 12KW On Grid Solar Inverter — frequently asked questions
What are the specifications of Solis 12KW On Grid Solar Inverter?
We hold 6 published specifications for this inverter, including depth 219 mm, height 563 mm, phase Three-Phase, type On Grid Solar Inverter and weight 18.8 kg. The full table is on this page, listed under model SOLS-20.
Who makes Solis 12KW On Grid Solar Inverter?
Solis 12KW On Grid Solar Inverter is a Solis product, listed under inverters with model reference SOLS-20. The Solis brand page lists the rest of its range so you can compare across the catalogue.
Is Solis 12KW 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. 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.
Where can I buy Solis 12KW 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.
