Our products are compatible with Tigo optimisers. You can use them to implement module-level monitoring on the Tigo platform.

You can download all our current certificates in the download area at https://www.fox-ess.com/downloads/

You can loop through the SmartMeter up to 80A, above 80A please use a CT Based Meter, which you must install according to the instructions (please note the direction of the arrows pointing to the house or to the mains).

You can loop through the SmartMeter up to 60A, above 60A please use a CT Based Meter, which you must install according to the instructions (please note the direction of the arrows pointing to the house or to the mains).

You can register your product at: https://warranty.foxesscloud.com/

The warranty starts on the day of commissioning (or 6 months after delivery of the product), whichever comes first.

You can connect min/max 1 – 8 EP batteries to the H3-Pro (3 ~ Hybrid 15-30 kW) and min/max 1-4 EP batteries to the H1 (1~ Hybrid 5-8-10.5kW).

In the old version of the cable lengths, we still supplied a 1.25 m battery cable. We have now adapted this to 3 metres. This should be suitable for most applications

Yes, that’s right. In the new release for the Fox Cloud we will show this separately. (PV yield and yield from the batteries)

In the Fox Cloud there is a setting ” Charge-Time ” where you can set how and when the unit is allowed to recharge (e.g. only from 8 am, until 8 pm).

No, with “Dual MPPT” strings of the same length (e.g. 18 modules or 20 modules) must always be used. With 2 MPPT, we advise the most symmetrical wiring possible, whereby different outputs are also possible.

The Wifi dongle is included in the delivery. The LAN dongle must be ordered separately. The EVO, The Beast, and Grid tied inverters all have built in WiLAN modules (WiFi + LAN).

The EPS port is only for emergency power supply. This means you should only connect loads to it that you absolutely need in the event of a load-shedding/reduction.

When installing a Fox ESS inverter alongside an existing inverter installation, a secondary smart meter/CT can be installed on the Fox inverter to monitor the existing inverters power output.

For South Africa, the inverter should be set to NRS_SA or NRS-097 depending on the available option.

Full Savings Mode: Set the minimum SOC to 10% and the minimum SOC (On-Grid) to 15%.

Power-Dependent Mode: Set the minimum SOC to 10% and the minimum SOC (On-Grid) to between 75% and 100%, depending on your load and backup requirements.

It is to protect the batteries and cells. The automatic safety or “fall-back temperature” is 3°C, and the standard recovery SoC is 60%.

At present, it is not possible to connect other “third-party products” with our inverters.

Charge your existing battery tower to a SoC of 50% (this is approximately the SOC at which the new slave should arrive). Then please measure the voltages at the DC (+ /-) contacts – here the voltage difference must not be greater than 0.5 V. If this is the case, you can easily add the new battery module to the battery tower and restart it (the BMS will then calibrate the entire tower).

Using the “Charge Time” function in the Fox Cloud, you can specify a “time window” for the inverter to charge.

The devices themselves, as well as the smart meter, have small measurement tolerances and measure time intervals. Certain minor deviations result from the measurement inaccuracies (power = voltage x current).

We only install updates after consultation and approval by the customer. This can be done remotely via the Fox Cloud or directly on the device via a USB (Vers 2.0 32GB) stick.

Some details for your Fox Cloud account can be edited once the account is created, however the username cannot be changed. If you believe the username is incorrect the account will have to be deleted and recreated.

Our team can reset account passwords upon request.

You can use the Wifi dongle (enclosed), if you do not have router reception in the basement, order the WLAN (wired) from MSPD .

As an installer, it is best to choose the “Installer” role. This gives you the most setting options in the Fox Cloud. You will then receive a so-called code (Installer Code) which you can give to the end customer during the installation when he logs into the Fox Cloud. In this way, the cloud knows which customer is assigned to which installer. This allows you to keep track of all end customer installations.

In the settings, the unit is set to STOP at the factory for safety reasons. This must be actively set to START directly on the display.

The password for pairing is : mtmt2020 and the inverter reports with a network starting with “W”. After pairing your smartphone to the inverter, you can connect to the Router
