BASIC HYBRID PV STORAGE SYSTEM OVERVIEW

INTRODUCTION

The H5001 hybrid inverter provides power to the essential load by utilizing power from PV panels, the utility and batteries. When the PV panels (two string input) generates enough power, the inverter supports the essential load, feeds back to the grid and charges the batteries, all at the same time. When the energy generated by the PV panels is not sufficient to support the essential load, the inverter takes power from the utility.

To accommodate various power situations, the H5001 is designed to handle continuous power from PV panels, batteries and the utility. When the MPP input voltage from the PV panels is within the acceptable range, between 250 and 430VDC, the inverter is able to feed the grid and charge the batteries. This inverter is only compatible with single crystalline and polycrystalline PV panels, and any other type of PV panels cannot be used.

Notes: When PV input voltage is lower than 250V, the power of the inverter will de-rate. This hybrid inverter has two PV

input.

Product Overview

Distribution Box

A wiring subpanel is pre-assembled at the factory. It consists of breakers, disconnects and batteries paralleled

circuits.

CAUTION. This inverter is heavy (87lb/40kg). Be carefully while lifting and mounting the unit. Installation should be handled by two people. Do not hang or place additional weight onto the inverter.

MOUNTING THE INVERTER

Before installation, make sure nothing inside the package is damaged. You should have received the following items in the package: H5001 hybrid inverter, backplate, brackets, screws and this installation manual.

The following considerations must be taken into account before selecting where to install.

• The unit cannot be mounted on flammable construction materials.

• The unit must be mounted to a solid surface.

• The unit should be installed at eye level in order to easily read the LCD display at any time.

• Allow 20cm (8in) of clearance to the sides and 50cm (20in) to the top and bottom of the unit for proper air

circulation to dissipate heat.

• The ambient temperature must be between 0 and 50°C and relative humidity must be between 5 and 85% to ensure optimal operation. Do not operate where the temperature and humidity are beyond the specified limits.

• The unit has a Pollution Degree rating of PD2. The unit must be mounted in a protected area that is dry, free of excessive dust and has adequate air flow.

• The unit was designed with an IP20 protection rating and is for indoor applications only.

Installing the Inverter onto the Wall

Step 1. Use the backplate as a

template, and install anchors as needed.

Note: If installing onto drywall, Unistrut needs to be mounted and secured to two studs in the wall. The backplate and inverter’s brackets are secured to the Unistrut using Unistrut lugs.

Step 3. Install the brackets onto each

side of the inverter.

Step 4. Hang the inverter onto the

backplate.

Step 2. Mount the backplate onto the wall.

Note: Use at least two screws, one on the left the other on the right.

Step 5. Secure the brackets on

inverters to the wall.

Note: Use at least two screws, one on each side of the inverter.

WARNING. Because this inverter is non-isolated, only two types of PV modules are acceptable: single crystalline and poly

current to the inverter. For example, non-grounded PV modules will cause leakage current to the inverter.

CAUTION. To reduce the risk of damage due to surge, Darfon recommends surge protection between the modules and the inverter.

CAUTION. Exceeding the maximum input voltage can destroy the unit. Check the PV string voltage before wiring the connection.

WARNING. Never touch the terminals of the inverter directly. It at the array not at the inverter.

DC CABLE FOR PV CONNECTIONS

PV MODULE (DC) CONNECTION

There is a DC (PV) circuit breaker in the distribution box. This system can connect to two strings of PV modules with MPPT control. Configure each PV input as recommended in the table below. Vmp is a PV panel’s max power point voltage. The PV charging efficiency is maximized when the PV system’s voltage is close to Best Vmp.

CAUTION. To reduce the risk of injury, use the proper cable size for PV module connection.

Connecting the PV Arrays

Step 1. For each PV input string, make sure the input voltage is between

250VDC and 430VDC, and the maximum current is 13A.

Note: The inverter can still be installed if you are only using one PV input string.

Step 2. Make sure the circuit breaker is off.

Step 3. Strip 15mm(0.6in) of insulation from each PV cable (PV1+, PV1-, PV2+

and PV2-).

Step 4. Insert the PV cables into the PV quick connect terminals. Make sure

the polarity for each connection is correct; positive to positive and negative to negative.
