At R-Fab, we focus on corporate energy management. But when shareholders and executives ask us to fix the energy mess in their private homes, we usually can’t say no.

One of our clients bought a house in Dzoraghbyur, a fast-growing Yerevan suburb with an aging, unreliable grid. Blackouts, voltage spikes, and harmonic distortions were a daily headache, frying sensitive electronics, wasting energy, and reducing solar efficiency.

The client travels for business, so his home has to run itself. He also has a small woodworking shop at home, which used to push his electricity bills up to $200 a month. On top of that, he’s an audiophile, and expensive speakers don’t play well with dirty electricity. His request? Get rid of all these problems permanently.

1. Smart Energy Management System

We started with the backbone of energy autonomy—a smart energy retrofit using an EcoFlow Smart Panel and a Delta Pro battery (3600W/7200W). Here’s what it does:

• Instant backup power – When the grid goes down, the switch to battery takes just 20ms. The client doesn’t even notice.

• Seamless generator start: If the outage lasts too long and the battery runs low, the system automatically starts a diesel generator.

• Smart load shedding – Critical systems (boiler, water pump, key lighting, essential outlets) are on a dedicated circuit. As the battery drains, non-essential loads get cut off first.

• Clean power for audio gear – The battery’s inverter powers a separate circuit for high-end audio. It double-converts electricity (AC to DC and back), ensuring a perfect sine wave: no hum, no distortion – just clean power.

• Solar-assisted charging – A 1.6 kW solar array keeps the battery up during the day.

Remote control – The client can manage everything from his phone, anywhere in the world

2. Solar Power Station

We installed a 7.2 kW solar power station to reduce electricity bills.

Solar in Armenia is nothing new, but this installation wasn’t straightforward. No south-facing roof and trees casting shadows throughout the day made things tricky.

Our approach:

• Shadow modeling – We ran a full shading simulation to map the best panel positions.

• Overbuilt the array – Extra panel capacity-optimized the cost-to-output ratio.

• Micro-inverters from NEP – Unlike traditional string inverters, these boost output by up to 30% in shaded conditions.

3. Smart Home Automation with Zigbee

Not everything in the house was ready for remote control; some systems were just not built that way, so we fixed that.

Example: The gas boiler shuts down automatically if the pipeline pressure drops. Restarting it requires pressing a button—useless when no one’s home. We solved it with:

• A gas analyzer to check if it’s safe to restart.

• A mechanical actuator (“robotic finger”) to push the boiler’s start button remotely.

The Results

• Electricity bills cut from $200 to $50 per month.

• No more blackouts—the system takes over instantly.

• No more audio dropouts—the power is always clean.

• No more worrying about the house while traveling—everything is accessible from a phone.

This retrofit transformed a fragile, outdated power system into a highly autonomous, intelligent energy system.
