SunGoldPower 12V Pure Sine Wave Inverter Charger + Optional 200Ah LiFePO4 Battery Bundle
Reliable off-grid power starts here. This SunGoldPower low-frequency pure sine wave inverter/charger is built for RVs, cabins, trailers, emergency backup, and mobile work setups where clean power and dependable charging matter.
Choose the configuration that fits your build:
Standalone Inverter (inverter/charger only)
Inverter + 2× LiFePO4 Batteries (200Ah total / 12V system)
This system supports common off-grid needs like powering lights, electronics, tools, small appliances, and charging your battery bank using shore power or generator input. Pure sine wave output means it’s safe for sensitive electronics, and the integrated charger helps keep your batteries ready when you need them.
Why this inverter setup is a smart choice
Pure Sine Wave Power Cleaner, more stable power than modified sine wave—better for sensitive devices and smoother motor performance.
Built-In Battery Charger + Transfer Function Charges your battery bank when connected to AC power (shore power or generator) and automatically switches power sources.
Low-Frequency Design (Heavy-Duty Reliability) Designed for demanding loads and real off-grid use in RV/trailer/cabin environments.
Multiple Working Modes Use your system the way you prefer with common inverter priority modes such as:
Battery priority
AC priority (shore/generator)
Perfect for:
RV & van builds
Off-grid cabins and tiny homes
Backup power systems
Mobile tools and job sites
Emergency preparedness setups
Understand Inverters & Batteries
1) What inverter wattage actually changes (2000W vs 3000W vs 4000W)
✅ It changes what you can RUN (power output)
Think of wattage like “how big of a load the inverter can handle at once.”
2000W = light-to-medium loads
3000W = medium-to-heavy loads
4000W = heavy loads / more headroom / fewer “overload” shutoffs
✅ It changes start-up ability (surge)
Motors and compressors have “startup surge” (fridges, pumps, power tools). Higher wattage inverters generally handle those start spikes better.
❌ It does NOT increase runtime by itself
Batteries determine runtime. A 4000W inverter doesn’t “use more power” unless the customer actually runs bigger loads.
2) What the batteries change (and how runtime works)
✅ Batteries change how LONG you can run devices
You’re offering 12V 200Ah total (two 100Ah batteries).
That equals roughly:
12V × 200Ah = 2400Wh (2.4kWh) of stored energy
Real usable energy after losses (inverter efficiency + battery safety reserve):
Expect ~1.9kWh–2.2kWh usable
✅ Batteries do NOT increase inverter watt output
They increase runtime and stability, not max output.
Important note (this is a big sales-saver)
At 12V, higher wattage loads pull huge amps:
2000W at 12V ≈ 167A
3000W at 12V ≈ 250A
4000W at 12V ≈ 333A
That’s why:
cables must be thick
connections must be tight
battery BMS must support high discharge
A bundle makes sense because the batteries are matched for current draw.
3) Quick runtime examples (with your 12V 200Ah bundle)
Using ~2.1kWh usable energy as a realistic average:
These are for people who want a “ready to run” kit — not just a component.
2000W + 2× 100Ah LiFePO4 (200Ah Total)
Best for: efficient off-grid runtime + basic home backup Typical use:
fridge + lights + phones
TV / router / Starlink
short microwave use Approx runtime examples:
300W load → ~6–7 hrs
600W load → ~3–4 hrs
1000W load → ~2 hrs Why choose it: best balance of runtime + power without extreme 12V current draw
3000W + 2× 100Ah LiFePO4 (200Ah Total)
Best for: customers wanting “real power” plus runtime in one bundle Typical use:
fridge + microwave + lights (not all maxed nonstop)
more appliances running together Approx runtime examples:
600W load → ~3–4 hrs
1200W load → ~1.5–2 hrs Why choose it: more surge capacity + still a practical battery starter pack
Important note: this setup pulls higher battery current than 2000W, so good wiring matters.
4000W + 2× 100Ah LiFePO4 (200Ah Total)
Best for: high-power tools or heavy short bursts (with proper wiring) Typical use:
high surge tools
bigger appliance loads (short duration) Runtime reality check: This is the highest power option, BUT the battery capacity is still 2.4kWh total. So if they actually run near 4000W, runtime is short:
2000W load → ~1 hr
3000W load → ~40 mins
4000W load → ~30 mins (ish)
Why choose it: maximum output capability — best for customers who care about running heavy loads, not long runtime.
