Page 11: Requirements For The Installation
Please make sure to fulfill all conditions below before installing and commissioning the Sunny Boy. 4.1 Requirements: Mounting Place The Sunny Boy 2800i has a relatively high weight of 31 kg. Please keep this in mind when selecting the place where and how to mount the Sunny Boy. - Page 12 5 cm Table 4.1: Minimum clearance If you want to install several Sunny Boy 2800i side by side on the same level, pay attention to the minimum distance between them. If there is not enough space between the devices, the left Sunny Boy will reduce the yield of the PV plant because of the incomming air temperature.

Page 13: Requirements: Pv-Modules
We recommend to install the inverter on a firm and sturdy surface. Mounting the Sunny Boy on a thin sur- face may emit a slight noise! SB2800i-11:SE0504 SMA Regelsysteme GmbH... - Page 14 Requirements for the Installation Installation Guide 4.2 Requirements: PV-Modules The Sunny Boy 2800i is designed for the connection of up to three strings (PV modules connected in series). The „ GenAu“ tool will help to dimension and check the size of your strings with respect to the Sunny Boy you intend to use.

Page 15: Requirements: Grid 230 V~ (Ac)
The relevant technical regulations as well as specific requirements defined by the local public utility have to be complied with. The terminals of the Sunny Boy 2800i are suitable for cables with The Sunny Boy has to be connected a cross-section of up to 2.5 mm². The Sunny Boy is connected with to grid with three wires! three wires (L, N, PE). - Page 16 Fig. 4.1: Losses in AC cable The Sunny Boy 2800i is designed for 230 V grids. The voltage should be within 198 V and 260 V and the frequency should be within 49.8 Hz and 50.2 Hz.

Thus, the module has three plus poles and three minus poles. These poles are simply connected in parallel within the inverter. In case only one String terminal is used, please cover the four plug-in contacts not used with the seals enclosed. SMA Regelsysteme GmbH SB2800i-11:SE0504... - Page 19 • Phase L to the terminal marked with „ 2“ • The terminal marked with „ 3“ is not used. 7. Make sure that all wires are firmly connected. 8. Push the socket tube firmly onto the socket. SB2800i-11:SE0504 SMA Regelsysteme GmbH...
- Page 20 Boy, insert the AC connector plug and tighten the seal. Do not switch on the circuit breaker yet! The Sunny Boy 2800i may only be connected to the AC grid when the PV strings have been connected and the device is tightly closed.
- Page 21 When you have found a ground fault in a string, only connect it to the Sunny Boy 2800i after you have removed the cause for the ground fault in the PV generator.
- Page 22 If the lower yellow LED repeatedly blinks once a second for four times, immediately disconnect the grid voltage and the PV generator from the Sunny Boy 2800i. The input voltage is too high. The inverter might be damaged! Check whether string voltages comply with limiting values stated in chapter 4.2 "Requirements: PV-Modules"...

Installation Guide Exchanging varistors Exchanging varistors The Sunny Boy 2800i is a very complex technical device. Therefore there are only a few possibilities to repair failures on site. Please do not try to make repairs other than described in this document. - Page 34 You can now check the varistors as described below while following the safety instructions given in chapter 2 "Safety Instructions" (p. 5). 6. Unscrew the lid of the Sunny Boy 2800i and remove it. Dis- connect the PE plug inside the lid. Test safe isolation from supply.
- Page 35 Installation Guide Exchanging varistors 11. Switch on the circuit breaker. 12. Check whether the LEDs of the Sunny Boy 2800i show trouble-free operation. If you have found neither a ground fault nor a defective varistor there probably is a fault in the inverter. Please contact the SMA hotline in this case to discuss further proceedings.
