EG4 3000EHV-48 Studio Build: Dedicated Solar for the Office and Production Space
When you’re filming solar content, there’s something that feels right about running your production equipment on solar power. The studio and office on this homestead are powered by a dedicated EG4 3000EHV-48 system — completely independent from the main home system.
This wasn’t just an aesthetic choice. Separating the studio load from the main home system made practical sense: production equipment, networking gear, and workstations have different power quality requirements than household appliances. A dedicated system means those loads are never competing with the AC compressor or the well pump for inverter headroom.
This post covers the complete studio build — why we went with the EG4 3000EHV-48, what loads it runs, how it’s wired, and the ATS installation that keeps everything running cleanly with or without grid backup.

Why a Dedicated Studio System
The homestead already had the EG4 12000XP running the main house and the EG4 6000XP covering a separate load group. So why add a third system for the studio?
Three reasons. First, redundancy — the studio and office need to stay up even if one of the main systems needs attention. Second, load isolation — production equipment runs cleaner on a dedicated circuit not shared with high-surge loads like the well pump or HVAC. Third, the 3000EHV-48 is purpose-built for exactly this kind of application: moderate, consistent loads that need reliable, clean power.
A dedicated system for your workspace or office is one of the most underrated solar builds. It’s smaller, simpler, and cheaper than a whole-home system — but it protects the equipment and the work that matters most to you. If the grid goes down in the middle of a recording session, this system doesn’t miss a beat.
What the Studio System Powers
- Production workstations
- Monitors and displays
- Networking equipment
- Camera charging stations
- Studio lighting
- Audio equipment
- Hard drive arrays / storage
- Office appliances
The total running load stays well under 3,000W in normal operation — which means the 3000EHV-48 is running comfortably below its capacity rating at all times. That’s intentional. Production equipment doesn’t get a second chance if the inverter faults mid-session.
Why the EG4 3000EHV-48
The 3000EHV-48 is a high-voltage battery compatible all-in-one inverter at 48V. For a studio application, the key specs that mattered were output power quality, battery compatibility, and the ability to run in EPS mode for seamless grid-to-battery transition.
Production equipment — particularly anything with sensitive electronics, hard drives spinning, or audio gear running — benefits from clean, stable power output. The 3000EHV-48 delivers that. We’ve had zero power quality issues with any of the studio equipment since the system went live.
Spec Worth Knowing
The “EHV” in 3000EHV stands for Extended High Voltage — it’s designed to work with higher voltage battery configurations. If you’re pairing it with a standard 48V LiFePO4 bank, confirm compatibility with your specific battery before purchase. Signature Solar’s team can confirm compatibility for your exact setup.
The ATS Installation
The ATS — Automatic Transfer Switch — is what makes this system truly seamless. When grid power is available, the ATS can route grid power to the studio as a backup charging source or pass-through. When grid power fails, the ATS switches to the inverter/battery system automatically — fast enough that running equipment doesn’t register the transition.
We filmed the complete ATS installation process for the OGSL YouTube channel. If you’re adding an ATS to your own system, that walkthrough covers the exact steps, the tools required, and the wiring sequence we used.
- Inverter mounting — Mounted in the studio in a ventilated location, away from direct heat sources and production equipment vibration.
- Battery bank connection — LiFePO4 48V bank connected to inverter with appropriately sized cable for the 3,000W load rating.
- ATS installation — Automatic Transfer Switch wired between grid input, inverter output, and studio load panel. This is the step most people skip — don’t skip it.
- Load panel connection — Studio loads connected to the output side of the ATS, fed by the inverter during normal solar/battery operation.
- Grid backup input — Grid tied to ATS as backup source — available for battery charging during extended cloudy periods.
- Monitoring setup — Connected to EG4 monitoring to track studio consumption and battery state independently from main home systems.
Don’t Skip the ATS
A lot of small studio and office solar builds skip the Automatic Transfer Switch to save money. The result is manual switching between grid and solar — which means a power interruption every time you swap. For production equipment, that interruption can corrupt files, crash sessions, or damage gear. The ATS pays for itself the first time the grid goes down mid-session.
How It Fits the Larger Homestead System
The studio system draws from the same 50kWh LiFePO4 battery bank and the same 21kW ground mount array as the main home systems. With 21kW of solar production during Texas daylight hours, there’s more than enough capacity to keep all three systems fully charged and running simultaneously.
The three-system setup on this homestead — 12000XP for whole home, 6000XP for secondary loads, 3000EHV-48 for studio — gives us true redundancy. Any single system can go down for maintenance without affecting the others. That’s not over-engineering. That’s how a real homestead operates.
