Cut your VINLEC bill.
Never lose power.
A Solar-First system runs your home on sun and battery by default — and switches to VINLEC automatically the moment you'd actually need it. No blackouts, no oversized battery bank, no guesswork.
One system, three sources, zero interruption.
Your home draws from the cheapest, cleanest source available at every moment of the day — and VINLEC only steps in as the safety net, not the default.
Solar powers everything
Panels run your home directly through the day and fully recharge the battery bank before sundown.
Battery carries the night
EG4 lithium storage runs your home silently overnight — sized to your actual night-shift load, not your whole day.
VINLEC catches the rest
If a run of storms drains the battery below a safe threshold, the inverter's built-in transfer switch flips to grid power instantly. Lights don't flicker.
Most homes don't need a bigger battery. They need a smarter one.
Because VINLEC is your backup, you only need enough battery to comfortably cover the night — not four rainy days in a row.
| Property | Daily use | Night usage | Battery bank |
|---|---|---|---|
| DIY eco-cottage | 8 kWh | ~4 kWh | 5 kWh (1× EG4-LL 100Ah) |
| Standard 3-bed home | 18 kWh | ~10 kWh | 10 kWh (2× EG4-LL 100Ah) |
| Small business | 35 kWh | ~15 kWh | 15–20 kWh (3–4× EG4-LL 100Ah) |
SOLAR ARRAY FORMULA
18 × 1.25 = 22.5 kWh needed → 22.5 ÷ 5.2 = 4.32 kW array → ≈10 panels at 450W.

Your Estimate
This assumes the battery covers your full day with no backup. Because VINLEC acts as your automatic safety net, most homes get away with a smaller bank sized to overnight use only — see the table above, or check recommended parts to size it exactly.
Everything is native 230V, hurricane-rated, and closed-loop.
All EG4 electronics — chosen for reliability in tropical heat, humidity and Caribbean grid conditions.
EG4 18kPV All-in-One Hybrid
Best for standard-to-large homes and small businesses. Pulls a clean single-phase line to a standard SVG breaker panel and handles heavy AC surge loads with ease.
Check price →EG4 6000XP Off-Grid
Best for DIY eco-cottages. A pure off-grid workhorse — parallel additional units later if your needs grow.
Check price →EG4-LL 48V 100Ah Server Rack
On-board LCD, closed-loop comms with EG4 inverters. One unit covers a tiny home's night shift on its own.
Check price →EG4 WallMount AW 48V 280Ah
One wall-mounted unit replaces a full rack of smaller batteries — a clean, space-saving footprint for mid-to-large homes.
Check price →EG4 6-Slot Server Rack
Houses up to six EG4-LL batteries with built-in busbars. Expand by sliding in a new module as budget allows.
Check price →Why LiFePO4, specifically
Unlike lead-acid or gel, these can be drained completely without damage — and are rated for 10–15+ years of daily cycling.
400–450W Monocrystalline
Heavy-duty aluminum frames and tempered glass, engineered for high wind loads and marine salt air — paired with proper hurricane racking.
Browse inventory →Cables & Class T Fuses
Pre-terminated 2/0–4/0 AWG battery cables and 200–250A fuse blocks. Order these with your main solar pieces so nothing gets stuck at the Miami dock.
Check price →Built around SVG's grid, climate, and import path.
Native 230V single-phase
No step-down transformers or workarounds — output matches SVG's standard breaker panel and appliances directly.
Hurricane and humidity rated
Tier-1 panels rated for high wind loads; batteries and inverters installed indoors, away from salty sea breeze and moisture.
Duty relief on solar panels
SVG's incentive programs can waive import duty on solar panels for qualifying buyers — check the official concessions page for current eligibility. VAT still applies.
No blackout during outages
Unlike grid-tied systems that shut off for safety, this hybrid setup keeps running independently through a VINLEC outage.
Your supplier ships to Miami. Your freight forwarder brings it home.
This is a well-worn path — thousands of us Vincentians use it every month.
Get a Miami forwarding address
Sign up with a freight forwarder (e.g. a Miami-based ocean cargo service) before you order. They'll issue you a personal Florida delivery address.
Check out with that address
Use your forwarder's address as shipping; your own billing details stay on the payment method. Order your inverter, batteries, and fittings like cables and fuses together in one shipment.
Choose ocean freight, pre-alert your forwarder
Solar equipment is heavy — sea cargo, not air. Upload your invoice to your forwarder's portal so they can clear US export customs.
Clear SVG customs
A local Kingstown customs broker is worth the fee to confirm what qualifies for duty relief under current concessions — this can vary by item and buyer status.
Pick up or forward to the Grenadines
Collect from the Kingstown warehouse, or have your forwarder route pallets onto the inter-island ferry for Bequia, Mustique, Canouan or Union Island.
This isn't theory. It's what's on my own wall right now.
I only recommend hardware I trust to protect my own home and investments — the battery bank running my home right now, EG4-LL and LifePower4 units in a single rack, was sourced the same way and freight-forwarded the same way outlined above.
They communicate directly with my inverter for fully automatic charging and night-shift discharge. When you buy the same rack and batteries through the links on this page, it's the exact hardware keeping my own lights on every night.

Straight answers before you buy.
Will this actually work with standard SVG appliances?
Yes. SVG's grid runs 230V single-phase at 50Hz. The recommended inverters output a native single-phase line matched to your standard local breaker panel — no converters needed.
Do I have to disconnect from VINLEC?
No — and you shouldn't. The system runs solar and battery first, with VINLEC wired in purely as an automatic backup that kicks in only if your battery drops below a safe threshold during extended storms.
Can the panels survive a hurricane?
The panels themselves are built for high wind and hail loads. Survival in a major storm comes down to using engineered aluminum racking bolted into rafters or a concrete slab — don't cut corners here.
How do the batteries handle tropical heat and humidity?
Install batteries, inverters and charge controllers indoors — a dry, ventilated utility closet or garage, off the ground, away from direct sun and salt air. That alone significantly extends their lifespan.
Do these suppliers ship straight to SVG?
Not directly. You'll ship to a Miami freight forwarder first, who consolidates your pallets and sails them to Kingstown by ocean freight — see the full import walkthrough above.
What about customs duty and VAT?
Solar panels can qualify for import duty relief under SVG's incentive programs, though eligibility depends on your buyer status and the specific item — see the official concessions page for current terms. Standard 16% VAT and port handling still apply, and a local customs broker can confirm exactly what qualifies for your shipment.
What if something breaks — how do warranty claims work?
EG4 and its authorized retailers offer multi-year warranties. For a physical replacement, you'd ship the faulty part back to your Miami forwarder for return to the US service center. Installing surge protection on both your solar and VINLEC lines helps avoid this entirely.
Stop guessing. Start building your system.
Every product above ships from vetted US suppliers and is ready to freight-forward to Kingstown.
