Growatt vs Solis Hybrid Inverter: Which Should You Quote? (Philippines)

Growatt and Solis both sit in the budget-mid tier of hybrid inverters sold in the Philippines, with a 5kW hybrid unit from either brand typically running ₱25,000-70,000. As with most budget-mid comparisons, neither brand has a documented, consistent performance edge over the other — the decision comes down to the specific model, warranty terms, and installer support.

How do Growatt and Solis compare at a glance?

Both brands overlap on price and positioning enough that the meaningful comparison is model-to-model, not brand-to-brand. See our hybrid inverter price guide for how pricing works across the budget-mid and premium tiers generally.

What actually varies between Growatt and Solis in practice?

• Distributor presence. Growatt has an established, named official distributor in the Philippines, which can mean more consistent parts and service access — but confirm this holds for your specific area and installer.
• Model-specific specs and features. Each brand spans several product lines; the exact model quoted matters more than the brand name for efficiency and feature comparisons.
• Warranty terms per SKU. Standard hybrid inverter warranties in the Philippines run roughly 5-10 years, with the exact term varying by model and sometimes extendable at a cost. Get this in writing.

What actually makes an inverter “hybrid” in the first place?

A hybrid inverter adds battery charging and discharging management, plus the ability to safely island your home from the grid during a brownout, something a plain grid-tied string inverter can’t do. Both Growatt and Solis build hybrid lines around this capability, typically priced roughly ₱20,000-45,000 above an equivalent grid-tied string unit of the same size. If backup power during outages is your actual goal, confirm the specific model quoted is genuinely from the hybrid line and not the cheaper grid-tied string line, since the two can look deceptively similar on a basic spec sheet. See our what is a hybrid inverter guide and our grid-tied vs hybrid vs off-grid solar guide for how that distinction shapes a full system design.

Does it matter whether I go with a three-phase or single-phase model?

Most Philippine homes run single-phase service, which is what standard residential Growatt and Solis hybrid inverters are built for. Larger homes, commercial spaces, or properties with three-phase utility connections need a three-phase-rated inverter, which both brands also manufacture, generally at a higher price point than the single-phase 5kW range this guide focuses on. Confirm your property’s phase configuration with your installer before comparing quotes, since a mismatched inverter simply won’t connect properly to your service.

How does this compare to Deye vs Growatt?

Deye also competes directly with Growatt and Solis in the same budget-mid bracket. The comparison logic carries over: check the model, price, and warranty rather than assuming a brand-wide winner. See our Deye vs Growatt inverter guide for that specific pairing.

What should you check before choosing?

1. Get the exact model number and datasheet for every quote, not just the brand name.
2. Confirm the warranty term in writing, including what voids it and whether paid extensions are available.
3. Verify battery compatibility for the specific inverter model if you’re pairing it with a LiFePO4 battery.
4. Ask about local parts and service turnaround for each brand from your installer directly, since that affects how fast you’d get support if the unit ever needs repair.

Bottom line

Growatt and Solis are close enough in price and tier that brand name alone shouldn’t drive your decision. Weigh the actual model, warranty, and installer support behind each quote before choosing.
