Elite Solar has commissioned 2 GW of cells and 3 GW of modules at Ain Sokhna, and utility plants built from them run 1,500 V DC strings. For the high voltage MLCC in the inverters and monitors on those strings, Venatech, Walsin’s authorised distributor in Hong Kong, supplies 914 Walsin parts rated 1,500 V to 4,000 V, 29 of them on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for power-electronics engineers and buyers in Egypt: inverter, optimiser, string-combiner and plant-monitoring makers in Ain Sokhna, the Suez Canal Economic Zone, 10th of Ramadan City and Cairo. Walsin Technology (Walsin) is the line we are authorised for. The Walsin figures come from our MLCC export (23,601 distinct part numbers) and our ready stock list as at 23 September 2026, re-measured on 11 November 2026. Every part number below is real.
What did Elite Solar commission at Ain Sokhna?
A cell and module plant aimed at export. Nanyang Technological University’s Centre for African Studies reported on 23 February 2026 that Elite Solar, a Singapore-headquartered American firm, commissioned its facility at Ain Sokhna in the Suez Canal Economic Zone with 2 GW of solar cell capacity and 3 GW of module capacity.
The NTU report, read on 11 November 2026, says the company announced a scale-up to 8 GW in 2024, projects annual sales above 190 million US dollars at full capacity, and targets the Middle East, Africa, Europe, North America and Egypt’s own market. These are the report’s figures. We covered this region’s module electronics before; this post is about the high-voltage side of the power conversion that follows the modules.
Why does a 1,500 V solar system need a high voltage MLCC?
Because every circuit that touches the string sees its full voltage. In a 1,500 V DC string inverter, optimiser or combiner monitor, MLCC sit in snubbers across the switching devices, in compensated voltage dividers that measure the string, in high-voltage filters and in gate-drive bootstrap paths, and each needs a rating above the highest DC voltage it will see.
The highest voltage is not the nameplate. A string’s open-circuit voltage rises on a cold, bright morning, and switching adds ringing above the DC level. Designers therefore rate MLCC well above the string maximum or place parts in series with balancing resistors. Class II X7R parts also lose a large share of capacitance under high DC bias, so a snubber value chosen at zero volts can be much smaller in operation; NP0 parts hold their value. Our post on MLCC DC bias and voltage derating explains the method.
How many Walsin MLCC are rated 1,500 V or more?
914 distinct part numbers. We counted 914 Walsin MLCC rated from 1,500 V to 4,000 V in our export, excluding the S2 safety series: 60 at 1,500 V, 472 at 2,000 V, 23 at 2,500 V, 299 at 3,000 V, 1 at 3,500 V and 59 at 4,000 V, split evenly between 457 NP0 and 457 X7R parts.
Add the 792 parts at 1,000 V and Venatech can cross to 1,709 Walsin MLCC rated from 1 kV to 4 kV, in cases from 0805 to 2225. Larger cases carry the larger values: at 2,000 V the X7R parts reach 47 nF in 1825, 2220 and 2225. On our Hong Kong shelf as at 23 September 2026 we counted 66 Walsin lines in that 1 kV to 4 kV band, 29 of them at 1,500 V or more.

The last three digits give the voltage: 152 is 1,500 V, 202 is 2,000 V and 302 is 3,000 V. Our post on how to read a Walsin MLCC part number covers the rest of the code.
What else should an Egyptian inverter team check?
Surface arcing, board flex and the effective value. We read our export for every one of the 914 parts at 1,500 V or more: it gives size, dielectric, value, tolerance and rated voltage, while surface-arc guidance, coating advice and capacitance under DC bias come from Walsin’s datasheet for the exact part.
Three checks matter most in desert plants. First, at kilovolt levels the air gap across the part’s own surface can flash over before the ceramic fails; a conformal coating and the right pad spacing address it. Second, large high-voltage cases crack under board flex, so keep them away from edges and fixings, or consider soft-termination high-voltage parts. Third, heat: inverter cabinets in Egyptian summers run hot, so check X7R behaviour at your hottest internal temperature.
How can Venatech help an Ain Sokhna power-electronics team?
How Venatech helps is a fast, field-by-field cross to an authorised source. VenaMatch at /cross-reference/ decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, returning every field marked match or mismatch, so a high-voltage capacitor from another brand comes back with its Walsin voltage, size and dielectric side by side.

How many Walsin MLCC are rated 1,500 V or more?
We counted 914 in our export, re-measured on 11 November 2026, from 1,500 V to 4,000 V, excluding safety capacitors. Venatech is Walsin’s authorised distributor in Hong Kong.
Is there a Walsin 1500V MLCC in 1206?
Yes. 1206B472J152 is 1206, X7R, 4.7 nF, plus or minus 5 percent, 1,500 V, and it was on Venatech’s shelf as at 23 September 2026.
What is the highest-value Walsin MLCC at 2 kV?
