Product overview
Suntree SISO-40 32A 4-pole DC isolator switch in Kenya rated to 1000VDC, with an interlocking lid, for safely isolating solar PV arrays.
Ensuring the safety of your solar energy system requires high-quality components like the Suntree SISO-40 DC Isolator Switch. This 4-pole device is engineered to handle the high-voltage demands of modern photovoltaic arrays, supporting up to 1000VDC and 1200VDC ratings. One of its standout safety features is the interlocking lid mechanism, which ensures the cover can only be removed when the switch is in the ‘off’ position, preventing accidental contact with live terminals. The unit is housed in a high-grade, UV-stabilized IP66 enclosure, making it completely dust-tight and protected against powerful water jets, which is critical for rooftop or outdoor mounting. Inside, the switch includes a dedicated earth terminal for secure grounding. Technically, the device meets DC-PV1, DC-PV2, and DC-21B standards, making it versatile for various system architectures. The extremely short power shut-off time of roughly 2ms is a benchmark in safety, effectively quenching arcs before they can cause damage to the equipment or pose a fire risk. Whether you are installing a residential 5kW system or a larger commercial array, the Suntree SISO-40 provides the professional-grade isolation required by international electrical standards. Its compact design allows for easy mounting on walls or rails, while the clear ‘on/off’ indicators provide immediate visual confirmation of the circuit status for technicians and homeowners alike.
Who it is for
Installers and facilities teams protecting PV strings, batteries and AC circuits with correctly rated breakers, isolators, surge protection and enclosures.
For business and commercial buyers
- Correct protection supports safe operation and insurance requirements.
- Itemised quotation and tax invoice from GeoSolar for your procurement file.
- Engineer review of compatibility with your existing system before you commit.
- Business pricing available to approved trade and corporate accounts.
Compatibility and installation
What to confirm before you buy
- DC or AC rating, and the maximum system voltage (for example 500VDC or 1000VDC).
- Current rating against the circuit it protects.
- Number of poles required by the circuit design.
- Enclosure IP rating and number of ways for the location.
Protection devices must be selected and installed by a qualified electrician. AC breakers are not interchangeable with DC breakers.

Frequently asked questions
Can I use an AC breaker on the DC side of my solar system?
No. DC circuits need DC-rated devices, which are designed to interrupt DC arcs. Use the DC rating that matches your system voltage.
Is the price VAT inclusive?
Yes. Marketplace prices are shown in Kenyan shillings and include 16% VAT where it applies. Your tax invoice shows the VAT amount.
How does delivery work?
Nairobi delivery is Ksh 1,500 and courier delivery to the rest of Kenya starts at Ksh 4,500; heavy items are quoted. Delivery is free on orders above Ksh 500,000, and you can collect your order instead.
Can GeoSolar install this for me?
Yes. Request a quotation and choose supply and installation. An engineer confirms the design and compatibility with your site before work starts.
Request a quotation
For project quantities, supply and installation, or when you want an engineer to confirm compatibility first.
