Glen Morris unpacks the latest cool solar and battery storage products at the Smart Energy Lab. SolarEdge have supplied their new ground breaking HD Wave inverter (light, powerful and easy to install) and Alpha ESS have supplied their new IP65 hybrid inverter/battery system called the SMILE5. It’s a 5kW hybrid inverter with dedicated backup circuit and multiples of 5.2kWh battery packs that can be stacked vertically or horizontally. Pretty cool looking unit.
New products (above) for my students to install on the next course (30 May – 2 June). On every course, suppliers generously donate equipment for my students to train on. Next week we have: Goodwe EM hybrid inverter, NicestESS 5kW AC battery system, Gen2 Pylontech LFP 2.4kWh batteries, Victron 250/100 MPPT, EasyWarm HotPV system, Outback FM60 MPPT, myWatt energy monitor, Sungrow SH5K+ hybrid inverter and backup box plus lots more.
The emphasis on our four day course is to blend theory and practice on a daily basis. The program starts with theory in the morning followed by practical sessions to reinforce and expand on the theory, returning to the classroom in the afternoon to explore the problems and solutions.
Many of the systems installed by students on this course are “real” systems. Above is a 1.5kWh/day system for the “Tiny House” located near the training centre. The house is a relocatable home for one person and has been designed from the ground up for minimal energy consumption. The solar panels the students installed were Solimpeks PVT (photovolatic and thermal) collectors. These unique panels combine water heating with electricity generation. Ideal for small roof areas such at this (7m x 2.5m).
“Beer o’clock” and system install review session! These “reviews” are part of the shared learning approach. Each team works on their own projects and come together at the end to present their experiences, likes and dislikes and problems.
Manfred explains how the Studer-Innotec d.c. coupled system works with Sonnenschein VRLA batteries.
Phil from Victron Energy shows the students how to program the 3kW Multiplus with 150/30 MPPT and ColorController.
“Capt. Col” working on the “Dream Team” – SP Pro + SolarEdge + LG Chem + Neuton Power VRLA. The concept of the “Dream Team” is to combine the high efficiency lithium battery with the low cost and depth of discharge capabilities of lead-acid batteries. The SolarEdge inverter meets the daily loads first from the LG Chem battery and only when depth of discharge limit is reached or the load power is greater than the power delivery limits of the lithium battery, is the lead-acid battery “called upon” via the Selectronic SP Pro to support the loads.
Ray carefully tensions battery terminals. Always use insulated tools when working on batteries with exposed terminals.
Ray & Adrian installing Studer XTM4000 and VarioTrack 150/80 MPPT. This d.c. coupled system gives high reliability and “battery centric” solar charging. D.C. coupling is a more reliable way of charging batteries and avoid the “black start” problem of a.c. coupled systems.
The “Tiny House” gets a power system.

Anthony checking the Goodwe GW2500-BP (yellow box) d.c. to d.c. converter that can be installed on the PV array side of any conventional grid-connect inverter – thus adding battery storage to an existing installation.
It always helps to read the manual!

Glen has just finished running another Australian Solar Council training course at Moora Moora Community Cooperative (Healesville, VIC). The focus of this course was on understanding solar PV hybrid and off-grid systems. The course had no prerequisites and attracted a wide range of participants wanting to learn more about renewable energy systems both on and off-grid.
Here’s a few photos.
