1,000W - 5,000W Inverters

1,000W to 5,000W Inverters: Sizing Between a 1.5 kW Solar Inverter and a 3kW Hybrid

Inverters from 1,000W to 5,000W are the range for RVs, vans, boats, workshops and small cabins, where the loads are a fridge, a microwave, power tools, a coffee maker and electronics rather than a whole house. If you have been searching for a 1.5 kW solar inverter, this is the collection: the units here bracket that size, from a 1,000W pure sine wave unit for a van to 3,000W hybrids that combine inverter, solar charger and battery charger in one box.

The collection lists 14 inverters from Rich Solar, Victron and Sungold Power at 12V, 24V and 48V. In-stock pricing starts at $219 for the NOVA PURE 1K and reaches $799 for the 3,000W NOVA MAX 3K hybrid and NOVA SUPERCHARGER 3K inverter charger. Every unit produces pure sine wave output, which is what sensitive electronics, medical equipment and variable-speed motors need.

How to choose an inverter in this range

• Continuous watts. Add the loads you run at once. Lights, a laptop and a 12V fridge stay under 1,000W, so the Rich Solar NOVA PURE 1K (1,000W continuous, 2,000W surge, under 3% THD) is enough. A microwave, a hair dryer or a small air conditioner pushes you to 2,000W or 3,000W: the NOVA PURE 2K or NOVA PURE 3K.
• Battery voltage. The inverter must match the bank. NOVA PURE 1K, 2K and 3K are 12V; the NOVA PURE MAX 2K and 3K are the same power at 24V. At 3,000W a 12V inverter draws roughly 250A from the battery, which is why 24V is the better choice at that size when you are building new.
• Plain inverter or hybrid. A plain inverter only converts DC to AC. The NOVA MAX 3K adds an 80A MPPT solar charger and a multi-stage battery charger, replacing three separate components in a cabin or RV build.
• Shore power and generator. If you plug into campground power or run a generator, the NOVA SUPERCHARGER 3K switches between shore, generator and battery in as little as 20 milliseconds and recharges the bank with a 150A charger.
• Certification. The NOVA PURE and NOVA PURE MAX units are UL 458 certified for use in RVs, trailers, vans and boats, which inspectors and insurers may ask about.

Setup and usage tips

• Check surge before continuous. Compressors and pumps draw two to three times their running watts at start-up; the NOVA MAX 3K and SUPERCHARGER 3K are rated for 6,000W surge for five seconds.
• Use the Solar Kit Calculator to confirm the inverter size alongside battery and panel sizing from your appliance list and ZIP code.
• Keep DC cables short and thick. A 3,000W 12V inverter needs heavy-gauge cable and a fuse close to the battery; place the inverter within a few feet of the bank.
• Match a hybrid's MPPT rating to the array. The NOVA MAX 3K's 80A charger at 24V handles a substantial panel set; confirm your string voltage stays within its input window.

Frequently asked questions

Is a 1.5 kw hybrid inverter available here? Not at exactly that size. The closest steps are the 1,000W NOVA PURE 1K below it and the 2,000W NOVA PURE 2K above; for a hybrid with built-in solar charging, the 3,000W NOVA MAX 3K is the entry point.

What is the difference between an inverter and an inverter charger? An inverter charger, like the NOVA SUPERCHARGER 3K, also charges the battery from shore power or a generator and includes a transfer switch. A plain inverter needs a separate charger for that.

Can I run a 12V inverter on a 24V battery? No. The voltage must match, so choose NOVA PURE for 12V banks and NOVA PURE MAX for 24V banks.
