Sofar Solar Energy Storage Inverter Faults and Repairs

Established in 2013 Sofar Solar launched the ME3000SP Energy Storage Inverter in the UK in 2015. The ME3000SP proved to be a very succesful add on for new systems but proved to be particularly popular with those looking to add energy storage to existing solar PV systems. The Sofar Solar system is AC coupled and works with any type of Solar PV system or when used purely for it's energy storage functionality with no solar at all.

As a result of their popularity we have become very familiar with repairing, servicing and diagnosing faults with Sofar Solar Energy Storage Inverters. The ME3000SP inverter has an LCD display on the front of the chassis. Identifying error codes shown on the display (assuming the display is working) is usually the best place to start in diagnosing the fault and getting systems using Sofar Solar Energy Storage inverters up and running again.

Sofar Solar ME3000SP Energy Storage Inverter Faults and Warnings:

Some of the advice we give related to identifying, confirming and or resolving some of the faults detailed below, starts with safely shutting down and restarting the inverter. This is something that nearly all solar PV and energy storage systems installed in the UK would have been designed to be carried out safely by the system owner. However, paperwork, schematics and manuals are not always clear or available, so if you have any concerns about how to do this, we will always be more than happy to talk you through the process over the telephone at no charge.

  • ID01 - GridOVP - The inverter is measuring a grid (mains) voltage that is too high in relation to the parameters that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.

  • ID02 - Grid UVP - The inverter is measuring a grid (mains) voltage that is too low in relation to the parameters that the inverter has been set to safely operate within. If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'. If automatic safety devices such as MCBs or RCDs have switched 'Off' then leave them 'Off' and contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter, the supply circuit or with the grid.

  • ID03 - GridOFP - The inverter is measuring a grid (mains) frequency that is too high in relation to the parameters that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.

  • ID04 - Grid UFP - The inverter is measuring a grid (mains) frequency that is too low in relation to the parameters that the inverter has been set to safely operate within. If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'. If automatic safety devices such as MCBs or RCDs have switched 'Off' then leave them 'Off' and contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter, the supply circuit or with the grid.

  • ID05 - Batt OVP - The inverter is measuring too much voltage from the batteries. Assuming that this is an existing installation that has been specified correctly, hasn't recently been changed or added to and has operated before without problems. This could mean either a problem with the batteries or with the inverter. We would advise that you Book an Engineer to test the DC side of the system including and excluding the inverter.

  • ID09 - HW_LLCBus_OVP - This is an internal error within the inverter. If after the system has been safely shutdown and restarted this condition persists then contact us.

  • ID26 - SwBusOVP - This is an internal error within the inverter. If after the system has been safely shutdown and restarted this condition persists then contact us.

  • ID27 - BatOCP - The inverter is measuring too much current from the batteries. Assuming that this is an existing installation that has been specified correctly, hasn't recently been changed or added to and has operated before without problems. This could mean either a problem with the batteries or with the inverter. We would advise that you Book an Engineer to test the DC side of the system including and excluding the inverter.

Mains/Grid Isolation and Surge Protection

Mains/AC Surge Protection Solar PV Systems

A whole house surge protector is installed to provide protection from transient overvoltages originating from the mains/grid. A whole house surge protector is installed directly inline and as close as possible to the incoming mains/grid supply meter, this allows for surge protection for all circuits and equipment including solar inverters, routers, stereos and other sensitive electrical equipment within the network. The addition of a 100Amp lockable isolator also allows for safe and convenient isolation of all electrical equipment within the network including consumer units, solar inverters, battery storage units and EV chargers from the mains/grid in one place.

Surge protectors are in compliance with the recently updated 18th edition amendment 2 of BS7671.

What Our Customers Say:

"Very decent with a helpful attitude and expert in the technical side and reliable too. Had to integrate with our roofers to use their scaffolding before and after their work to take down and reinstall our PV panels. Helpful scheduling. Up and running again to our satisfaction at a decent price." David Ballard, Ramsbury
