TECHNICAL COMMENTS
Hybrid Controllers – Most narrowboats have 12v electrical systems. Those with a solar array charge them with a simple solar controller. A hybrid controller adds the option of mains electricity up to a maximum of 1500w at any one time without the need for a separate inverter.- Power Stations – Connected directly to any solar array, a power station is a highly effective way to add more battery storage, mains electricity, and a wide range of other power outlets including USB and 12v.
Detailed Technical Comments
Narrowboat solar panels are an easy way to make life on the cut much less costly without too much hassle. Panels rated at 400w now cost little over £100! Fitting 5 gives 2000w nominal output. Knowing how much power you would like is the essential first step. Our Electricity Consumption Estimator comes with a nifty extension that also shows you roughly what you can expect by way of daily solar production, month by month. Contact Us for your FREE copy.
The sections below are guides to what you need to consider before buying anything. Please take the time to read that on Energy Management & Storage. That decision controls so many others. Consider too the advantages of the new large capacity LifePo4 batteries that save both money and space.
Simple Controllers.
These devices are connected to your solar array and their sole purpose is to charge your batteries. Two technical controller technologies are offered – PWM and MPPT. The former is cheaper but some 20% less efficient, and we do not advise it.
Our chosen suppliers are Epever and Ecoworthy. We have good personal experience with both and they are compatible with both lead/acid and lithium batteries. Capacities run from 20 to 60A and what you need is directly linked to the power output of your solar array. The output of a typical 400w 24v panel is 17A. All our controllers will accept 12 and 24v panel output, but for 48v only one does. Please choose carefully.
Hybrid Controller/Inverters
combine the functions of MPPT solar charge controllers, mains charge controllers, and 230v mains inverter in a single, low-cost, easily installed unit. With 12v batteries, the inverter output is however limited to 1500w. The 3 and 5Kw products need to be connected to 48v batteries.
Our chosen suppliers are Epever, EcoWorthy, and EASun with all of whom we have personal experience.
THE RIGHT DECISION.
What is right for you will be determined first by the nature of your narrowboat’s primary electrical installation. If it is 12v with some 230v, then a hybrid controller/inverter is an excellent solution subject always to not needing inverter output of less than 1500w. If your boat is primarily 230v then a hybrid inverter and 48v domestic batteries will be the best solution if you decide against a power station. If you have 12v domestic batteries and need more than 1500w of mains power then a large capacity 12v to 230v inverters will be the only viable solution.
Power Stations have long been the favourite of outdoor campers, as well as motor-home and camper van owners. With the greater storage and inverter capacities now available, they deserve the close attention of narrowboat owners.
In a single package, they provide
- MPPT solar controller,
- a large LifePo4 battery, and
- extensive AC, DC, and USB power outlets.
They can be charged from solar, the mains, a generator, or another external battery.
Power stations can be divided into three broad product types: small, medium, and large. The latter are not relevant to a narrowboat.
- Small portable units designed to be moved around for use as a mobile source of electricity. Most are usually charged by portable panels. They store 1Kw of electricity and offer the same inverter output.
- Medium-sized units with inverter ratings of 2, 3, and 5Kw. Batteries are of 2 and 3Kw capacities and up to 4 can be connected to a single unit. The 2Kw models are keenly priced- those of 3 and 5Kw remain relatively expensive. None in this category can handle more than 1200w of solar input but mains/generator power can add another 500w. On a narrowboat that is unlikely to be an issue.
We are distributors of the Bluetti range. An AC200Max is part of our houseboat system. It has been invaluable. These medium-sized units offer an outstanding solution for narrowboats. They provide a total easily installed solution. For instance the AC200Max that we have offers a 30A 12v outlet and 4 x 230v AC plugs as well as an array of USB outlets to charge phones and laptop computers. Because they can be charged directly from the alternator when there is insufficient sunshine, they allow the power and safety of lithium without additional equipment and installation cost.
The 2Kw models like the AC200Max are very keenly priced but the inverter capacity will be a problem for some. In practice it means that you cannot use more than one domestic appliance at a time. If the dishwasher is in use, no toaster or coffee machine! Maybe not a big deal!
Our solar hot water controllers are an established favourite on sailing yachts. Owners long ago discovered the comfort of having free hot water from surplus solar energy, and it is thanks to them that we realised that not having hot water was not only a problem/need on sailing yachts, but on all boats, and at remote off-grid land sites. Our solution is much easier to install than thermal panels and much safer than gas – always a hasard on a boat. It is ideal for a narrowboat.
The digital controller unit is connected to your 12 or 48v domestic battery bank (lead/acid or lithium) and from there on to your water heating element either directly or via a 230v mains connection. The default configuration switches on the heating element if
- 12v battery voltage is greater than 12.2v (51.2v for 48v)
- solar panel output is greater than 900w (prevents accidental use when there is insufficient solar input)
- water temperature is less than 40°C and not over 52°C
This means that you are using any surplus solar energy to heat your water. There is a manual over-ride so that you can turn on the system even if solar output is insufficient.
The system needs a solar installation of at least 1000w and 48v battery capacity of 2400w. We know what works with what, and, more importantly, what doesn’t. We can help you make the right purchase decisions for your precise circumstances. To help us best help you, complete the Project Appraisal Form and we will gladly advise you.
