SolarEdge inverters  

It's quite amazing what some intense competition can do. Before Huawei arrived with their very clever Hybrid with optimisers, SolarEdge were very expensive. That's all changed now. SolarEdge are fighting hard and prices have plummeted, at least for the time being. The biggest cut has been in the battery interface. Not surprising really because Huawei has it built in. The SolarEdge SESTI battery interface for HD Wave has gone down from $1690 to just $700 overnight!!

The first thing about SolarEdge is that the product line up can appear very confusing, so let's try and keep things simple with 3 rules.

Rule 1

Every solar panel MUST have a DC optimiser (cost $75 each) fitted. You cannot selectively deploy optimisers with SolarEdge. So a typical 24 panel system will have $1800 worth of optimisers. If you don't know what these do, read this

Rule 2
If you want an emergency circuit to partly power your home from batteries during a mains power failure, then you MUST buy the StorEdge model. The HD-Wave does NOT have backup. (This may change in the future but as of March 2018, this is the case)

Rule 3
If you want batteries then StorEdge is the only model with the battery interface built in.

HD-Wave requires a SESTI battery interface ($700)

In other words StorEdge is a hybrid inverter, HD-Wave is not, but can be made to be.

StorEdge comes as a single phase 5kW ($2565) or 6kW single phase ($2880)

HD-Wave comes as a single phase in these sizes...

2.5kW, 3KW, 3.5kW, 4.6kW, 5kW and 6kW
The most popular is the 5kW, just reduced in price from $1860 to $1550.

There is also a 3 phase 5kW ($2100), 7kW ($2220) and 8kW ($2410) range which is neither an HD-Wave or StorEdge, and as it neither supports batteries (at all) or has backup, it's a bit pointless. Most people get one or two single phase HD-Wave inverters instead.

The other bits and pieces

WIFI ($90 extra per inverter)

Smart energy meter inc CT clamp ($350) for batteries

SESTI battery interface for HD-Wave ($700)
P370 optimisers (60 or 72 cell panels up to 370W) $75

SolarEdge HD-Wave also has other toys for charging your electric vehicle or remotely connect to your home to switch surplus solar power over to your pool pump or A/C unit. Another time for these...
