<p class="callout info">This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [easy-pv.ie](https://easy-pv.ie) versions of Easy PV. The information provided here may not be accurate for easy-pv.com.</p>

To add a custom panel in Easy PV navigate to **My Components** &gt; **Solar Panels** on the left-side menu or **Components** &gt; **Edit Solar Panels** from the top drop down menu.

You will need the **datasheet** from the manufacturer so Easy PV can appropriately perform calculations for inverter sizing and system output. Below you will find guidance on how the information in the datasheet corresponds to the values Easy PV asks for.

#### **Creating manufacturer** 

When adding any custom panel in Easy PV you first need to add a custom manufacturer category which allows you to organise your custom components. The components added will be categorised by their manufacturer when it comes to select them in a project.

#### **Inputting information from datasheet** 

You will then need to input the technical information found in the datasheet for the panel. If your data sheet has two sets of data you should use the values for **standard test conditions (STC)** not the values for Normal Module Operating Temperature (NMOT). This is a list of potential variations for each value required to add a custom panel:

</td></tr></tbody></table>

</div></div>The panel will auto-save once all the required fields are completed. Once you have added a panel successfully, you’ll be able to select it in the list of panels when creating a new project in the panels task, listed under your custom manufacturer name.

#### **Additional details and rules** 

- The **photo** and **description** for the panels will show up on your final customer proposal, to edit the image of the custom manufacturer or component, click on the default image and upload from your files.
- There is a set of rules which you can select or deselect as you need, these are the default settings for new panels: [![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2024-10/scaled-1680-/PBOLVPgei9DDS1Qg-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2024-10/PBOLVPgei9DDS1Qg-image.png)

# Custom inverters

<p class="callout info">This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [easy-pv.ie](https://easy-pv.ie) versions of Easy PV. The information provided here may not be accurate for easy-pv.com.</p>

To add a custom inverter in Easy PV navigate to **My Components** &gt; **Inverters** on the left-side menu or **Components** &gt; **Edit Inverters** from the top drop down menu.

You will need the datasheet from the manufacturer so Easy PV can appropriately perform calculations for inverter and battery sizing and system output. Below you will find guidance on how the information in the datasheet corresponds to the values Easy PV asks for.

### **Manage your own inverters**

#### **Step 1: Add an inverter manufacturer group**

To add an inverter, you first need to ensure you have an appropriate inverter manufacturer group set up. Click on the **Add inverter manufacture option** and **input a name** for the inverter manufacturer group and then **press enter on your keyboard or click out of the name field**. Once you've done this the page will update to show the new manufacturer group that you've added.

Next re-open your custom manufacturer group and a**dd a description** and s**elect the type of inverter** you will add to this inverter group. You can set the type as PV inverters, hybrid inverters or AC-coupled inverters. You can only add one type of inverter to each inverter manufacturer group, so if you want to add specific PV inverters (also known as a string inverter) and hybrid inverters you will need a separate group for each.

[![Create an inverter manufacturer group.gif](https://help.easy-pv.co.uk/uploads/images/gallery/2025-05/ks1A5HpXhdUyFdyM-create-an-inverter-manufacturer-group.gif)](https://help.easy-pv.co.uk/uploads/images/gallery/2025-05/ks1A5HpXhdUyFdyM-create-an-inverter-manufacturer-group.gif)

#### **Step 2: Add a specific inverter model**

To add a specific inverter model, first **navigate to the inverter manufacturer group you want to add it to**. Click on the **Add inverter** button and **add the name, description and model number**. These details are displayed in the customer proposal, so add information that is useful and compelling for your customer.

You can also add the following details at this stage:

- ENA system reference - this is used for DNO applications and can be found on the ENA Connect Direct portal.
- Price - this is the price that will be used in the financial task for any projects that include this component

#### **Step 3: Add technical information from the product's datasheet**

Finally, add all the technical details for the product. These are needed in order for Easy PV to correctly use the inverter in your projects. You can normally find the data needed on the manufacturers data sheet. If data is missing please contact the manufacturer directly.

[![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2025-05/scaled-1680-/xT4gOQkKvc0BDX65-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2025-05/xT4gOQkKvc0BDX65-image.png)

Below is a list of definitions and the potential variations for each value on different manufacturer datasheets for each section for PV, hybrid and AC-coupled inverters.

##### **AC output** 

As well as whether it is a single phase or three phase inverter, other than max power for AC inverters, all inverter types you will need to input the following information:

# Custom battery

<p class="callout info">This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [easy-pv.ie](https://easy-pv.ie) versions of Easy PV. The information provided here may not be accurate for easy-pv.com.</p>

To add a custom battery in Easy PV navigate to **My Components** &gt; **Batteries** on the left-side menu or **Components** &gt; **Edit Batteries** from the top drop down menu.

You will need the datasheet from the manufacturer, below you will find guidance on how the information in the datasheet corresponds to the values Easy PV asks for.

<p class="callout info">If your custom battery is not showing up in the inverter task, see the 'Rules' section and check the compatibility is correct.</p>

#### **Inputting information from datasheet** 

Below is a list of definitions and potential variations for each value on different manufacturer data sheets:

<div class="pm-table-container with-shadow-observer" data-layout="custom" id="bkmrk-technical-info-varia"><div class="pm-table-wrapper"><table data-layout="default" data-number-column="false" data-table-width="760" data-testid="renderer-table" style="width: 100%;"><colgroup><col style="width: 49.2304%;"></col><col style="width: 50.7696%;"></col></colgroup><tbody><tr><th aria-sort="none" class="ak-renderer-tableHeader-sortable-column__wrapper" colspan="1" rowspan="1">**Technical info**

</td><td colspan="1" rowspan="1">- Battery module energy
- Battery system capacity

</td></tr><tr><td colspan="1" rowspan="1">**Max Discharge:** maximum depth to which the manufacturer recommends that this battery is discharged. Typically 80 or 90%.

</td><td colspan="1" rowspan="1">- Depth of discharge

</td></tr><tr><td colspan="1" rowspan="1">**Round Trip Efficiency:** percentage of electricity recovered from the battery in a charge-discharge cycle. Around 95% is typical for lithium ion batteries.

</td><td colspan="1" rowspan="1">- Peak round-trip efficiency

</td></tr></tbody></table>

</div></div>The battery will auto-save once all the required fields are completed.

#### **Rules**

Notice you can select a variety of rules for the battery. Some key points:

- It is important you select which inverter groups or which specific inverters the battery is compatible with - either by checking 'Selected inverter groups only' or 'Selected specific inverts only' and selecting from the menu which inverters it is compatible with.
- If your hybrid inverter is an **all-in-one system** and you would like it to appear in one line in the quote then make sure to input the price in the **inverter** and then select 'exclude from shopping cart' in the **battery** rules - this means it will only include and list the cost of the inverter and not the batteries. Note that this will mean additional batteries will not be priced if more than one battery can be included.

# Custom accessories and other components

<p class="callout info">This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [easy-pv.ie](https://easy-pv.ie) versions of Easy PV. The information provided here may not be accurate for easy-pv.com.</p>

To add a custom accessory in Easy PV navigate to **My Components** &gt; **Accessories** on the left-side menu or **Components** &gt; **Edit Accessories** from the top drop down menu.

In Easy PV you can also add custom AC isolators, DC isolators and meters. Each of these will be available to select in the electrical task, with accessories in the **Extras** section of the electrical task.

[![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2025-01/scaled-1680-/qdf0l687ljMbGkCC-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2025-01/qdf0l687ljMbGkCC-image.png)

These are largely more straight forward than other components in Easy PV. However, when adding a custom accessory, there are many different rules you can select. To determine what each rule changes, select the rule and a window will appear which details what the rule will change about how the component can be used
