Installing an element-optimized solution such as SolarEdge can be a little confusing for the first time if all your previous experience is with traditional string inverters. It can also be a liberating practical experience for PV installers. Along with a SolarEdge installation a lot of the standard design steps can be entirely eliminated, giving an installer unrivaled flexibility when completing a great installation. The SolarEdge method has features that many fitters new to the technology are generally not yet fully aware of, in like manner help fill in the gaps this is a difficult guide to the differences you’ll come across when installing your first SolarEdge PV system.
Get online
We strongly recommend that you should constantly connect your system to the internet. This may not be an essential step for the method to work and your customer may still get all the great things about shade resistance from the method, however, if internet access can be acquired, get it connected. Being online gives you and your customer the use of the free SolarEdge tracking portal, allowing you to monitor the total system right down to the module stage. If something is not working because it should, SolarEdge will also be capable of troubleshooting the system remotely, important support, especially for your first number of installs. The connection is made by using a standard Ethernet cable from the inverter to the householder’s router or perhaps a connection can be made easily using the Zigbee option. Several installers also use Netgear Ethernet, for connection over strength line plugs; although this technique usually works perfectly well, remember it is not the SolarEdge reinforced solution.
Choosing the correct windows optimizer
Most standard 60-cell 250Wp photovoltaic modules work with the solar edge OP250 250W Grid Optimizer. Still higher power modules just like the forthcoming LG NeoN or perhaps thin film modules including the Solar Frontier need a diverse optimizer. Installers can combine different optimizers on a method, even on the same string, which means for example you can have a line of 2 x Hyundai 250s, 2 x LG Fluorescents 300s, 2 x Solar power Frontier 155s, 2 back button Kyocera 190s, and a couple of x UpSolar 245s: ideal for putting together a test device in your offices.
No highest string voltage
You don’t need to bother about maximum string voltage and also traditional string design. No matter the module panel being used, an individual always has the same condition. For individual phase systems, you must have at the very minimum 8 and a maximum of twenty-five optimizers per string, or even a maximum current of 15A per string. For three-period systems, you need a minimum of 12-15 and a maximum of 50 optimizers per string, or all over again a maximum of 15A per cord. You do not need to put modules with different roofs onto several strings, for instance, you can have a new 16-module system having 6 panels on the distance roof, 5 on the sth, and 5 on the gulf roof, all on the same cord. Be wary of making the mistake (for example on a 14-board east-west system) of positioning 7 modules on each cord as this will bring you under the minimum of 8 required.
It truly is preferable for all 14 solar panels to be on the same string. To get a 16-panel east-west you will have the choice, depending on what is more hassle-free.
Six optimizers must be earning a living for the system to work. Therefore, any design should mean that it is recommended to have at least 6 quests in sufficient sunlight actually generating something, so in an 8-module system, no more than 2 modules may be completely shaded.
Communication involving the optimizers and inverters is now over the DC power line. As a result, there is no need to install any added communication cables meaning there is not any risk of wireless interference.
Placement the optimizers
Mount each of the optimizers in position on the increasing rail before placing in addition to connecting the PV web template modules. The optimizers can be associated with our standard Alpha vía using a standard Rail to help Roof Hook Connection Set as though it were a new module clamp together with however washer. Once configured, observe the position of the optimizers for the layout. The optimizers include stickers that you can peel off, in addition, to sticking to a layout list. There is also an iPhone app readily available which can scan the bar codes and record the position. Acquire the SolarEdge App the following. The layout can then be sent to SolarEdge, which uploads it on top of their monitoring portal permitting you to view and see the modules on your system in their correct opportunities.
Test the string discord before connecting the inverter
When the optimizers are not coupled to the inverter they produce a ‘safe’ 1 V voltage to get fire safety allowing you to compute tell how many optimizers you have. For instance, if you have 12 in a very strong and there is sunlight, then you definitely should measure 12 / on the string. If this can never be assumed, then there may be a connection blunder. A bad optimizer does not cease the system from working. The commonest fault on a SolarEdge put up is a bad connection manufactured between the module and the windows optimizer. This optimizer will not do the job but all the other optimizers will probably continue working, so make sure the string voltage goes your number of optimizers.
Comprehensive Inverter/Optimizer pairing in day
The pairing will not be held properly in the dark. If I really enjoy seeing the install has been past due, pairing can be done remotely, provided that you have connected the inverter to the internet.
Use a 3G router
If any of your installs have no internet connection, then buy a 3 G router for times when you should troubleshoot those sites. These days there are 3G routers such as Zoom capability that can connect to the internet throughout your smartphone, a cost-effective way to make it possible for SolarEdge remote access to any issue sites you might have.
