• Before installation, check the unit to ensure it is free of any transport or handling damage, which could affect insulation integrity or safety clearances. Choose the installation location carefully and adhere to specified cooling requirements. Unauthorized removal of necessary protections, improper use, incorrect installation, and operation may lead to serious safety and shock hazards or equipment damage.
• Before connecting the inverter to the power distribution grid, contact the local power distribution grid company to get appropriate approvals. This connection must be made only by qualified technical personnel.
• Do not install the equipment in adverse environmental conditions such as in close proximity to flammable or explosive substances; in a corrosive environment; where there is exposure to extremely high or low temperatures; or where humidity is high.
• Do not use the equipment when the safety devices do not work or are disabled.
• Use personal protective equipment, including gloves and eye protection during the installation.

• Liabilities arising from commercial components are delegated to their respective manufacturers.
• Any time the inverter has been disconnected from the public network, please be extremely cautious as some components can retain charge sufficient to create a shock hazard.
• Before touching any part of the inverter please ensure surfaces and equipment are under touch with safe temperatures and voltage potentials before proceeding.

PE Connection and Leakage Current PV System Residual Current Factors

• In every PV installation, several elements contribute to the current leakage to protective earth (PE). these elements can be divided into two main types.
• Capacitive discharge current – Discharge current is generated mainly by the parasitic capacitance of the PV modules to PE. The module type, the environmental conditions (rain, humidity) and even the distance of the modules from the roof can affect the discharge current. Other factors that may contribute to the parasitic capacitance are the inverter’s internal capacitance to PE and external protection elements such as lighting protection.
• During operation, the DC bus is connected to the alternating current grid via the inverter. Thus, a portion of the alternating voltage amplitude arrives at the DC bus. The fluctuating voltage constantly changes the charge state of the parasitic PV capacitor (i.e capacitance to PE). This is associated with a displacement current, which is proportional to the capacitance and the applied voltage amplitude.
• Residual current – if there is a fault, such as defective insulation, where an energized cable comes into contact with a grounded person, an additional current flow, is known as a residual current.

Residual Current Device (RCD)

All Energizer Force S Series inverters incorporate a certified internal RCD (Residual Current Device) to protect against possible electrocution in case of a malfunction of the PV array, cables, or inverter (DC). The RCD in the Energizer Force S Series inverter can detect leakage on the DC side. There are 2 trip thresholds for the RCD as required by the DIN VDE 0126-1-1 standard. A low threshold is used to protect against rapid changes in leakage typical of direct contact by people. A higher threshold is used for slowly rising leakage currents, to limit the current in grounding conductors for safety. The default value for higher speed personal protection is 30mA, and 300mA per unit for lower-speed fire safety.

Installation and Selection of an External RCD device

• An external RCD is required in some countries. The installer must check which type of RCD is required by the specific local electric codes. Installation of an RCD must always be conducted under local codes and standards. Energizer Force S Series recommends the use of a type-A RCD. Unless a lower value is required by the specific local electric codes, the Energizer Force S Series suggests an RCD value between 100mA and 300mA.
• In installations where the local electric code requires an RCD with a lower leakage setting, the discharge current might result in nuisance tripping of the external RCD. The following steps are recommended to avoid nuisance tripping of the external RCD.

1. Selecting the appropriate RCD is important for the correct operation of the installation. An RCD with a rating of 30mA may trip at a leakage of 15mA (according to IEC 61008). High-quality RCDs will typically trip at a value closer to their rating.
2. Configure the trip current of the inverter’s internal RCD to a lower value than the trip current of the external RCD. The internal RCD will trip if the current is higher than the allowed current, but because the internal inverter RCD automatically resets when the residual currents are low it saves the manual reset.

Surge Protection Devices (SPDs) for PV Installation

WARNING!

• Over-voltage protection with surge arresters should be provided when the PV power system is installed. The grid-connected inverter is not fitted with SPDs on both the PV input side and the mains side.
• Lightning will cause damage either from a direct strike or from surges due to a nearby strike.
• Induced surges are the most likely cause of lightning damage in the majority or installations, especially in rural areas where electricity is usually provided by long overhead lines. Surges may impact both the PV array conduction and the AC cables leading to the building. Specialists in lightning protection should be consulted during the end-use application. Using appropriate external lightning protection, the effect of a direct lightning strike on a building can be mitigated in a controlled way, and the lightning current can be discharged into the ground.
• Installation of SPDs to protect the inverter against mechanical damage and excessive stress include a surge arrester in case of a building with an external lightning protection system (LPS) when separation distance is kept. To protect the DC system, a surge suppression device (SPD type) should be fitted at the inverter end of the DC cabling and the array located between the inverter and the PV generator, if the voltage protection level (VP) of the surge arrester is greater than 1100V, an additional SPD type 3 is required for surge protection for electrical devices.
• To protect the AC system, surge suppression devices (SPD type2) should be fitted at the main incoming point of AC supply (at the consumer’s cutout), located between the inverter and the meter/distribution system; SPD (test impulse D1) for signal line according to EN 61632-1. All DC cables should be installed to provide as short a run as possible, and positive and negative cables of the string or main DC supply should be bundled together.
• Avoiding the creation of loops in the system. This requirement for short runs and bundling includes any associated earth bundling conductors. Spark gap devices are not suitable to be used in DC circuits once conducting; they won’t stop conducting until the voltage across their terminals is typically below 30 volts.
