What these specifications mean
Tesla VMIII 4kW off-grid Solar inverter is listed with 18 published specifications from Tesla Solar, including battery voltage of 24 VDC, efficiency of 90%~93%, transfer time of 10 ms (For Personal Computers); 20 ms (For Home Appliances) and operating humidity of 5% to 95% Relative Humidity(Non-condensing). 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.
Before you buy an inverter
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
Tesla VMIII 4kW off-grid Solar inverter is listed at ₨ 112,000 (PKR). 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 your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Tesla Solar locally before ordering.
Tesla VMIII 4kW off-grid Solar inverter — frequently asked questions
How much does Tesla VMIII 4kW off-grid Solar inverter cost?
Tesla VMIII 4kW off-grid Solar inverter is listed at ₨ 112,000 (PKR). 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 Tesla VMIII 4kW off-grid Solar inverter?
We hold 18 published specifications for this inverter, including battery voltage 24 VDC, efficiency 90%~93%, transfer time 10 ms (For Personal Computers); 20 ms (For Home Appliances), operating humidity 5% to 95% Relative Humidity(Non-condensing) and rated power 4000VA/4000W. The full table is on this page, listed under model TESA-88.
Who makes Tesla VMIII 4kW off-grid Solar inverter?
Tesla VMIII 4kW off-grid Solar inverter is a Tesla Solar product, listed under inverters with model reference TESA-88. The Tesla Solar brand page lists the rest of its range so you can compare across the catalogue.
Is Tesla VMIII 4kW off-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. 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.
Where can I buy Tesla VMIII 4kW off-grid Solar inverter?
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 — buying in-channel is what keeps the manufacturer's warranty valid.
