Some of the exciting new systems at the Smart Energy Lab
Raj showing Mark how to commission the NicestESS 5kW AC coupled battery inverter. This unit can be used to add energy storage to any existing PV inverter system. The NicestESS unit is wired between the existing PV inverter and the switchboard to which it connects. The unit takes 48V Pylontech US2000B batteries.
Shaun and Steve discuss the Victron Energy system being installed into the new IP54 enclosure from Power Plus Solutions. The inverter is the new AS/NZS 4777.2:2015 compliant Multigrid 3kW hybrid inverter. The battery system is a GenZ pack of up to 6 x 3kWh units in the cabinet below.
Midwinter training courses at the Smart Energy Lab
Chula from Sungrow shows the students how to program the SH5K+ hybrid inverter.
New 5kW hybrid from Goodwe, the “EM” model. Same power rating (5kW) as it’s big brother (ES) but with a reduced 50A maximum battery charge/discharge current.
Upgrading an existing Outback system by adding another FM60, Hub and Mate3.
Configuring Suntrix’s myWatt inverter monitor.
Swapping over the GiantPower IPS4000 under harsh weather conditions.
Using the Solar Pathfinder to assess the solar window of a site.
Rachel doing a BMS hardware swap-over on the older Pylontech US2000A batteries.
Installing the new Imeon Energy 9.12kW hybrid inverter.
Duncan MacGregor from Enphase explaining how the Enphase system works.
Stage one of installing the EasyWarm “HotPV” system.
Networking at the end of the day on a cold winter’s night.
Mark configuring the EasyWarm system for both VOV and GT mode.
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.

December 2016 Solar + Storage Course
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.

Students install new Aquion BMS to integrate with Sunny Island 8.0H
The SMA Sunny Island inverter was primarily designed to work with lead-acid and (with the latest firmware) lithium ion battery systems. Integrating a non-lithium/non lead-acid battery with the Sunny Island has proved problematic, however, Aquion have solved the problem by building the DataTap device (BMS) that “emulates” the characteristic of a lithium battery BMS while managing the coulombic charging of the Aquion aqueous hybrid ion battery using it’s own current shunt.
