Product FAQ's

What is the MAX solar input on the Walrus G4 Plus?

The Walrus G4 Plus supports up to 8,000W of solar input via a single MPPT input port. However, the MPPT has strict electrical input requirements:
-Voltage Range: 90V – 230V DC
-Max Current: 80A DC
-Only One MPPT Input Port

⚠️ Panel Configuration Limits
If you're using BatteryEVO’s 550W solar panels (Voc = 49.9V, Isc = 14.0A), you cannot connect 8 panels in series — doing so would exceed the MPPT voltage limit:
-2 panels in series (2S): Voc = 99.8V
-5 panels in series (5S): Voc = 249.5V → ⚠️ Exceeds 230V voltage limit
-Up to 8 panels in parallel (8P): Isc = 14A × 8 = 112A → ⚠️ Exceeds 80A current limit

💡 Recommended Safe Configuration:
We suggest a 2S4P or 4S2P setup (8 panels total), which keeps the voltage and current within the MPPT input range:
-Series Voltage: 99.8V or 199.6V (within 90–230V)
-Parallel Current: 56A or 28A (within 80A)
-Total Nominal Power: 8 × 550W = 4,400W

This is well below the 8,000W max, but it ensures safe operation and efficient performance. Overloading voltage or current may trigger faults or damage the MPPT.

How long can a G4 Plus battery power my home or devices?

The Walrus G4 Plus comes equipped with a 23 kWh NMC battery and a built‑in 13 kW (16.5 kVA) inverter, capable of powering both 120 V and 240 V appliances. It’s built to handle whole‑home or heavy off‑grid use, depending on your actual energy consumption.

On a full charge, it can typically run:
-A refrigerator, lights, internet, and electronics for 2–3 days
-Or heavier loads like mini-splits, laundry, microwave, water pump, or tools for 10–15 hours depending on usage.

Full Home Backup:
If your home uses ~25–30kWh/day, the G4 Plus can typically cover most of a full day’s energy, including HVAC, fridge, lights, electronics, etc.
Pairing it with solar panels (up to 8,000W) allows for continuous recharge during sunlight hours, significantly extending runtime.

Output Capability for Power-Hungry Loads:
1. 13kW continuous output can handle:
-Electric oven + microwave simultaneously;
-Central AC + well pump;
-Power tools, induction cooktops, etc.
2. 240V/50A output = compatible with most home breaker panels, RV plugs, generators, and emergency circuits.

Recharge Capability:
When paired with a solar setup within the MPPT input range (90–230 V DC, ≤ 80 A) — for example, using BEVO 550 W panels in a safe 2S4P or 4S2P configuration — the system can recharge from 0 to 100% in roughly 4–6 hours of strong sunlight, depending on weather and orientation.

Whether you’re looking for emergency home backup, full off-grid living, or powering an RV garage / workshop, the Walrus G4 Plus offers enough capacity and power to reliably support your lifestyle.

Can I install this system myself, or do I need a professional?

The Walrus G4 Plus is designed with ease of installation in mind. It includes:
-A built-in inverter, battery, and charge controller;
-Preconfigured connections and internal BMS;
-Standard AC output via SS2-50P (twist-lock) or NEMA 14-50R plug.

If you have prior experience with off-grid or backup power systems, basic setup is plug-and-play. However, for new off-grid environments, we highly recommend hiring a licensed electrician — not only to safely wire AC loads and input, but also to help set up a dedicated sub-panel to isolate critical circuits from the main grid (if any), ensuring proper load balancing and safety.

This ensures that your system is up to code, operates safely, and protects both your devices and your solar investment.
