Verified Customer

We only had one good section of roof facing the right way, so the number of panels was always going to be the limit. Going with the 475W modules meant we got the system size we wanted without covering the whole house. Tidy job and the black frames look far better than the older panels on our street.

Quote explained what would fit and why, and the install ran to the day we were given. Six months in and the output is tracking where we were told it would. No complaints at all.

How much solar panel capacity can I connect to my EK70 HS5 10kW Single Phase inverter?

While this is a 10kW inverter, the recommended maximum PV array power is  20,000W. Known as oversizing your solar array, it allows your system to gather more energy during cloudy days or early mornings when sunlight is low. The inverter will then cap the alternating current (AC) power sent to your home or the grid at its rated 9,999 watts. This configuration maximises your total daily energy yield.

What does the 4 MPPT specification mean for my roof layout?

Having four separate trackers means you can split your solar panels across up to four different roof areas or orientations. If one part of your roof experiences shade or a poor sun angle, it won’t drag down the performance of the panels on the other parts of the roof, ensuring greater efficiency. 

Does the EK70 HS5 10kW Single Phase inverter provide backup during a blackout?

Yes. The built-in 63A whole-home backup bypass function switches your home over to battery power in 10 milliseconds or less during a blackout. This transition is so fast that appliances will stay on without resetting. Additionally, it can output a massive short-term peak of up to 20,000 watts for 10 seconds.

How many batteries can I stack with this system?

You can stack between 2 and 6 modular SAJ EK70 BU5 battery units per inverter. This lets you scale your energy storage capacity seamlessly as your household power needs grow. 

Can the EK70 HS5 inverter withstand harsh Australian weather?

Yes, the IP66 weatherproofing rating means this inverter can withstand heavy rain, dust, and debris. Combined with thermal aerosol fire suppression, the system is designed to release a fire-suppressing aerosol when triggered by a fire-related event, helping control potential fires within the battery system. The automatic smart air cooling system in the inverter also manages internal temperatures to prevent overheating.
