10kva solar inverter 48

*Solar Inverter 10kVA 48V: A Robust Solution for Medium‑Scale Solar Systems*

The *10 kVA 48 V solar inverter* is a hybrid power‑conversion unit designed to bridge the gap between solar panels, battery storage and the electrical grid (or a generator). By handling up to 10 kVA (≈8 kW) of apparent power and operating from a 48 V DC bus, it’s a popular choice for residential, commercial and small‑scale industrial installations where a medium‑size backup is required.

Core Features
Feature What It Means for You
High Power Rating (10 kVA) Supports multiple high‑power appliances (air‑conditioners, pumps, lights, computers) simultaneously.
48 V Battery Bank Works with common deep‑cycle lead‑acid or lithium‑iron‑phosphate (LiFePO₄) batteries, giving flexibility in capacity sizing.
Pure Sine‑Wave Output Delivers clean, grid‑quality power for sensitive electronics, reducing humming and heat in devices.
MPPT Charge Controller (built‑in) Maximizes solar harvest by tracking the panel’s maximum power point, typically 145 V–500 V open‑circuit voltage.
Hybrid/Grid‑Tie Capability Can feed excess solar energy back to the grid (if net‑metering is allowed) or work off‑grid with automatic switchover.
Programmable Settings Set priority for solar → battery → grid, schedule timers, and adjust low‑voltage disconnects via LCD panel or mobile app.
Protection Suite Over‑voltage, under‑voltage, overload, short‑circuit, reverse polarity, and temperature safeguards.
Compact, Wall‑Mount Design Saves space and simplifies installation in switch‑rooms or outdoor enclosures.

Why Choose a 10 kVA 48 V Inverter?
1. *Scalable Energy Storage* – The 48 V platform lets you stack batteries in series/parallel to achieve the desired autonomy (e.g., 5 kWh → 20 kWh+).
2. *Future‑Proof Flexibility* – Hybrid logic lets you start with solar‑only and later add grid tie or a generator backup without replacing the unit.
3. *Cost‑Effective Performance* – Higher voltage reduces cable losses and allows longer runs between the battery bank and inverter.
4. *Reliability in Harsh Conditions* – Robust protection and wide temperature tolerance make it suitable for Nigeria’s hot, dusty climates.

Typical Applications
– *Residential Solar Systems* – Powers lights, fans, TVs, and a few high‑power appliances during daytime and night.
– *Small Commercial Shops* – Keeps POS terminals, refrigeration, and security systems online 24/7.
– *Remote Sites (Telecom Towers, CCTV)* – Provides reliable backup where grid is intermittent.
– *Hybrid Solar‑Generator Setups* – Allows seamless transition between solar, battery, and diesel generator.

Installation Tips
– *Sizing the PV Array*: Aim for a peak power of 1.2 × – 1.5 × the inverter’s rated capacity (≈12 kW – 15 kW of panels) to fully utilize the MPPT window.
– *Battery Bank*: Use 4 × 12 V deep‑cycle batteries in series (48 V) with a capacity of at least 200 Ah for a realistic 2–3 hours backup at full load.
– *Cable Gauge*: Keep DC runs ≤ 3 m and use ≥ 35 mm² copper cable to minimize voltage drop.
– *Earthing & Lightning Protection*: Install a proper grounding rod and surge protector on both AC and DC sides.

Maintenance & Monitoring
– *Routine Checks*: Inspect connections, tighten terminals, and clean dust from vents quarterly.
– *Battery Health*: Log voltage, charge/discharge cycles, and temperature; replace batteries when capacity drops below 70 % of original rating.
– *Remote Monitoring*: Use the built‑in Wi‑Fi or GSM module to view real‑time data and receive alerts for faults.

Bottom Line
A *10 kVA 48 V solar inverter* blends power, efficiency, and flexibility, making it an excellent choice for Nigerian homes and businesses seeking reliable solar backup and reduced electricity costs. With intelligent hybrid logic, robust protection, and easy expandability, it delivers today’s energy needs while staying ready for tomorrow’s upgrades.
