APPLICATION NOTE AP003a – HOW TO USE DARFON H5000 AS EMERGENCY POWER IN PUERTO RICO
The Off-Grid Solution: H5001 Hybrid Inverter
During September of 2017, hurricane Maria rendered most Puerto Ricans without power at home, possibly for many months to come. Night satellite images of Puerto Rico before and after hurricane Maria are shown in the images below.
Here Darfon presents an energy solution for immediate application to Puerto Rico during the blackout period, and for future prevention of power loss at home.
When the utility grid is down, the best solution for continuous home power is to use photovoltaic (PV) modules coupled with a hybrid inverter and a battery array. Darfon’s H5000 hybrid inverter can operate in an off-grid environment. It can accommodate up to 6.5kW of PV modules, and has a built-in charger for charging 48V battery banks.
The H5001 hybrid inverter is nominally 5kW of AC output and allows a short burst up to 7kW. It can accommodate 2 strings of PV modules with individual MPPT for maximum power. The built-in battery charger can charge at 60A and discharge at 150A. The inverter is bidirectional which allows charging the battery from the grid.
World Technology offers the H5001 for utilization in your market for Water filtration and desalination, Hospitality & Tourism, Disaster Response & Emergency Preparedness, Defense & Security, Commercial & Water agencies and Aid & Development requirements.
For more specifications of the H5000 please refer to the datasheet below.

The H5001 comes with the H5000 hybrid inverter and includes quick disconnect terminals, AC breakers, PV disconnect and battery connectors, making the system easy to install.
The Darfon H301, H302 is also one of the most cost competitive ESS systems in the market for residential and light commercial applications and is available for utilization in your market today!
H300 Energy Storage System
Model Number: H301, H302
About H301, H302:
The Darfon H300 hybrid energy storage system is a wall-mountable pre-configured solution that consists of a H5000 hybrid inverter, distribution box, and 5kWh Lithium battery (LNMC). The is a solution for those with a limited budget, a light load to support or without much floor space. The distribution box is attached and prewired to the H5000, so there are only two products to mount. The distribution box includes quick disconnect terminals for AC, DC, and generator, AC breakers, PV disconnect, and battery connectors, making the system easy to install.
If you have a limited budget, a light load to support and don’t have the floor space, then the H300 series is the solution for you. The H300 series of hybrid storage systems are wall-mountable pre-configured solutions consisting of a H5001 hybrid inverter and 5kWh Lithium batteries (LNMC). In this series, the H301 has a storage capacity of 5kWh and the H302 has 10kWh. And if the need arises, the H301 can easily be upgraded into the H302.
