+263 78 922 2847The Ultimate Guide to Solar Accessories & On-Grid System Protection Kits
Product Guide By: Sona Solar Zimbabwe (Technical Team) | Status: Available Now
A professional solar installation requires more than just panels and an inverter. A solar power system is a massive, long-term financial investment. Leaving it unprotected against unpredictable grid fluctuations, load-shedding surges, and indirect lightning strikes is a risk you simply cannot afford to take.
The On-Grid System Protection Kit & Complete Accessories Range from Sona Solar Zimbabwe is expertly engineered to offer comprehensive, 360-degree security for your expensive hybrid inverter, lithium batteries, and sensitive home appliances. We have assembled the highest-grade protective components, mounting hardware, and automation controls to ensure your system operates safely and efficiently for years to come.
Why Choose This Kit? It provides absolute peace of mind by enhancing system safety, dramatically extending the lifespan of your components, and ensuring strict electrical compliance for residential homes, corporate offices, and commercial setups.
DON'T RISK YOUR INVERTER
Voltage spikes when ZESA returns can instantly fry unprotected circuitry. Ensure your solar installation meets international safety standards with our pre-configured protection kit and high-quality accessories. Order Your Kit Today
Detailed Component Breakdown
Unpredictable spikes from the grid or indirect lightning strikes can instantly destroy the sensitive microprocessors inside an expensive hybrid inverter. These components act as your primary, fast-acting shield.
DC SPD (Surge Protection Device)
Placement: Between your solar panels and the inverter.
Function: This crucial device safely intercepts massive direct current power surges caused by atmospheric electrical activity (lightning). Instead of allowing the surge to travel down the cables and fry your inverter's MPPT charge controller, the SPD violently diverts the excess voltage straight into the earth.
AC SPD (Surge Protection Device)
Placement: On the grid (ZESA) input side of your setup.
Function: Whenever the national grid experiences a sudden high-voltage spike—which is very common the second power is restored after load-shedding—the AC SPD acts as a gatekeeper. It grounds the surge before it can breach the inverter's AC input board, saving both the inverter and your connected home appliances.
AVS Digital (Automatic Voltage Switcher)
Function: This is an intelligent, digital real-time monitoring unit. It constantly reads the incoming grid voltage. If the power drops too low (brownouts, which can damage compressor motors in fridges) or spikes too high, the AVS instantly disconnects the power supply. It then enters a safe "wait mode" until the voltage stabilizes within acceptable parameters before safely reconnecting the power.
Safe maintenance, emergency shut-offs, and short-circuit prevention require dedicated, specifically-rated heavy-duty breakers for each distinct power source in your system.
Battery MCB DC (Double Pole & Single Pole)
A high-amperage direct current miniature circuit breaker specifically designed for the massive currents drawn by solar batteries. We stock sizes ranging from 32A, 63A, to 125A DC DP and SP Breakers. It protects your expensive lithium-ion or gel battery banks from catastrophic short circuits and allows technicians to safely isolate the batteries during maintenance.
PV MCB (Double Pole)
This specific direct-current breaker sits between your roof solar array and the inverter. It prevents excessive fault currents from the solar panels from overloading the system. It also serves as a mandatory quick shut-off switch, allowing you to "turn off the sun" going into the inverter when performing cleaning or maintenance.
AC Input & AC Output Protection (All Sizes)
These are dedicated alternating current breakers that manage power flowing into and out of the inverter. We stock all required sizes for domestic and commercial loads.
Input Protection: Guards the inverter from drawing dangerous, unchecked currents from the national grid.
Output Protection: Ensures that if a severe short circuit occurs somewhere inside your house, the breaker trips instantly, preventing the fault from back-feeding into the inverter.
A professional solar installation is not just about the equipment; it is about how neatly it is organized, ensuring safety, aesthetics, and allowing the user easy, intuitive control.
Manual Changeover Switches (63A)
A robust, heavy-duty manual transfer switch. In the event your solar inverter requires maintenance or completely fails, this switch allows you to safely bypass the entire solar setup with a single flick, routing grid or generator power directly to your home's distribution board.
DB Boxes (HT Enclosures)
We supply premium, surface-mounted Distribution Board boxes in 5-Way, 8-Way, 12-Way, and 15-Way HT configurations. These house all your breakers, SPDs, and AVS units in one central, safe enclosure. It eliminates messy "spaghetti wiring" and protects sensitive components from dust and accidental contact.
Grounding, Fuses & Arrestors
Complete your safety matrix with our heavy-duty Fuses & Holder DP 160A for massive battery banks, alongside certified Grounding components and Lightning Arrestors to ensure total discharge safety.
Upgrade your system from manual operation to smart, automated power management.
Auto Changeover Switches (1-Phase & 3-Phase)
Remove the need to manually flip switches when the grid fails. Our 1-Phase and 3-Phase Auto Changeovers detect power loss and instantly switch your load to solar or generator backup, providing a seamless transition for critical business or home operations.
Fridge Timers
Protect your refrigeration units. Fridge timers enforce a mandatory delay before reconnecting power after an outage, allowing the compressor gases to settle. This tiny device prevents massive damage to expensive appliances.
The physical foundation of your solar array must be built to withstand extreme weather and prevent theft.
Solar Mounting Rails & Roof Hooks
We stock high-grade aluminum Solar Mounting Rails, alongside specialized Tile Roof Hooks and IBR Roof Hooks to securely fasten your panels without compromising your roof's waterproofing.
Anti-Theft Brackets (Small & Medium)
Protect your panels from theft. Our specialized anti-theft brackets make it exceedingly difficult for unauthorized removal of your array from the roof structure.
Premium Solar Cabling
Power is lost through cheap wires. We provide UV-resistant 6mm Solar Cable for optimal panel-to-inverter transmission, heavy-duty 25mm Battery Cables to handle massive amp draws, and robust Multi Core (AC) Cables for safe grid connection.
Installing a solar system without proper protection is like driving a high-performance sports car without insurance or seatbelts.
Most major inverter manufacturers (like Deye, Sunsynk, and Must) will void your warranty if they determine that a failure was caused by an external surge and the system was not fitted with adequate SPD and breaker protection. This kit is your insurance policy.
